Abstract: The purpose of this paper is to identify trends in natural resource economics as reflected in publications in JEEM over the period since its inception in 1974. A secondary purpose is to suggest an explanation for any patterns we observe in the data. The data base consists of all articles published during this period, classified by topic and method. We apply statistical techniques of increasing sophistication to determine the existence of trends, and interpret the results by appealing to what we characterize as forces of demand and supply.

Abstract: This paper reviews the impact of the literature in depletable resources and energy economics over the period 1973–1998, particularly the initial period of publication of the Journal of Environmental Economics and Management, 1974–1998. A discussion of prominent policy issues in this arena is provided, along with an indication of what academic economics papers have contributed to that debate. This is followed by a citation analysis of contributions in the fields of energy and exhaustible resource economics. For each of these two fields, a list of the top papers in each five-year period from 1974 to 1998 is presented, along with a list of the top journals in each decade, based on average citations per article. The top ten cited articles in the fields in the Journal of Environmental Economics and Management are also presented.

Abstract: This paper considers whether the Journal of Environmental Economics and Management (JEEM) has had impact on the development and applications of the methods used to estimate economic values for non-marketed environmental resources. Journal editors control the research dialogue in a discipline and as a result have the potential to influence its scope and direction. At least four areas of research have been influenced by JEEM, the theory and practice of contingent valuation, the use of preference restrictions in valuation, the development and application of corner solution models, and the role of substitution between environmental resources for valuation.

Abstract: The efficiency of Giridih coal and crushed coconut shell in removing cadmium from solution was investigated in batch experiments after eliminating other sorbents in the initial screening tests. Both sorbents were found to adsorb cadmium from solution. The batch sorption kinetics and equilibria may be described by a first order reversible reaction and Freundlich isotherm respectively. The first order rate constant for forward and reverse reactions have been calculated for both sorbents. In order to establish the rate limiting step the pore and film diffusion coefficients were evaluated from the half time equations. Film diffusion appears to be rate limiting. The cadmium adsorption for both the sorbents was found to be a function of pH of the reaction mixture, which increased with pH increase up to pH 10. A decreasing trend in sorption was observed beyond pH 10. The mechanism of sorption in terms of electrostatic forces and chemical interactions has been indicated with the aid of zero point of charge (pH_zpc).

Abstract: The technology of adsorption has evolved within the past few decades as the front line of defense of the water and waste treatment industries for control of hazardous organic chemicals. In many ways, the evolutionary track of the technology reflects the changes that have occurred in the philosophical and scientific directions of the environmental engineering field over the same period. The evolution of a scientific basis for the technology has enlightened our understanding of others, for the phenomenon of adsorption operates in virtually every water and waste treatment process and every process that occurs in the natural aquatic environment. The objectives of this paper are to present a perspective of the historical and modern origins and motivations for adsorption technology in environmental applications, what we know of the science of the process, our ability to articulate that knowledge in engineering design, and a look toward technological horizons.

Full Text: 1984\J Env Eng-ASCE110, 976.pdf

Abstract: The adsorption of phenol and substituted phenols on activated carbon was examined. Mixtures of phenolic compounds were employed to test the Ideal Adsorbed Solution (IAS) theory using an improved method of calculation that had been developed for the description of multi-component adsorption. This improved method of calculation allows for equilibrium concentrations to be calculated independent of the experimental observations as previously required in the original work. The IAS model with the modified calculation method was tested for its performance on ten sets of binary and tenary phenolic mixtures. The Langmuir competitive model was used for comparison. The IAS model was found to be successful in precisely describing the competitive adsorption behavior of phenolic mixtures and was proven to be superior to the Langmuir competitive model in all cases studied. The IAS model was also found to be relatively sensitive to the single-component isotherm parameters input to the model calculation, particularly at low adsorbate concentration.

Full Text: 1987\J Env Eng-ASCE113, 285.pdf

Abstract: The influence of culture condition on the production of extracellular polysaccharide, protein, and its effect on the removal of Cu(ll) by activated sludge solids is investigated. The surface of sludge particulates grown in low C/N ratio are found to be high in protein but low in polysaccharide content. Both polysaccharide and protein are important to Cu(II) adsorption. The optimal pH values for Cu(II) adsorption are between 5.5 and 6.0. The decrease in Cu(II) adsorption density at pH > 7 is attributed to the deterioration of biomass. Soluble COD as high as 190.4 mg/L was detected at pH 9.4. The organic ligands will chelate the Cu(II) ions to form soluble organic complexes that are not adsorbable. Surface loading plays an important role in Cu(II) adsorption. The adsorption of Cu(II) onto the sludge particle surface can be described by a modified Langmuir adsorption isotherm that incorporates the effect of proton. It is found that [H⁺] behaves as a competitive inhibitor.

Full Text: 1987\J Env Eng-ASCE113, 1074.pdf

Abstract: Cadmium, copper, and nickel removals during the activated sludge process are investigated using a pilot scale plant. Cadmium and copper are predominantly insoluble in the settled sewage and have high percentage removal efficiencies. Nickel is mostly soluble in the influent and is poorly removed. Batch studies undertaken on mixed liquor samples at different solids concentrations indicate that a major removal mechanism for cadmium and copper is the interaction of particulate associated metal with the settleable biological solids, whereas uptake of soluble metal dominates for nickel. Titration of free metal ions with the mixed liquor solids and extracellular polymer indicates that the latter is responsible for some of the metal immobilization. The low resolubilization of copper by ethylenediaminetetraacetic acid and the calculated metabligand stoichiometry of less than unity indicate copper’s high affinity for mixed liquor. Stoichiometrics greater than unity for cadmium and nickel suggests that their removal is mechanistically dissimilar to copper.

Full Text: 1988\J Env Eng-ASCE114, 962.pdf

Abstract: Cadmium removal efficiency of chitosan is studied using batch experiments. Studies indicate that sorption kinetics as well as capacity are highly favorable for using chitosan as an adsorbent. There is a significant increase in sorption capacity with a decrease in particle size of chitosan. Cadmium removal is pH dependent and increased up to pH 8.3. The presence of chloride ion and ionic strength has no significant effect. Heavy metal ions such as zinc and soluble complexing agents such as ethylenediamine tetracetate (EDTA) decrease the sorption of cadmium. Used chitosan can be regenerated with acid and reused. Column studies using cadmium spiked tap water show that the presence of calcium, magnesium, bicarbonate, and chloride ions in tap water do not affect the cadmium removal capacity of chitosan.

Abstract: Hydrologic considerations, such as the water storage capacity of peat, are critical in properly designing peatlands for wastewater treatment. Water storage capacity is estimated by measuring the specific yield of peat in a north Michigan cedar swamp. Field estimates of specific yield are performed by measuring the response of water table to rainfall. Specific yield, taken as the ratio of rainfall to water table rise, is found to decrease exponentially with depth, ranging between 0.4-0.7 for the surface layers and between 0.05-0.15 for peat layers at 0.5 m depth. A model predicting the water table response to rainfall is developed and successfully tested. Applications of the model in designing wetland wastewater treatment systems include computation of maximum wastewater quantity that can be sprinkled on a wetland before flooding and overland flow. Such information is critical in systems where optimum treatment is to be achieved when wastewater is absorbed into the peat matrix.

Abstract: The adsorption of two dyestuffs from aqueous solutions onto bagasse pith was studied using an agitated batch adsorber. A three-resistance mass transfer model, based on external mass transport, macropore diffusion, and micropore diffusion, was used to predict concentration versus time decay curves. The predicted curves were correlated with experimental data for up to 24 hours in order to determine the three mass transport parameters.

Abstract: For highly urbanized cities where there is a scarcity of available land for landfilling, incineration may be a better method of solid-waste disposal. After incineration about 20% by weight of ash and other residues are produced. Both the washed clinker and fly ash collected from the refuse-incineration plant have the prerequisite properties for use in geotechnical applications. The washed clinker is essentially a granular material of irregular shape. Fly ash is predominantly siltsized, spherical particles. The specific gravities of the washed clinker and fly ash are 2.67 and 2.45 respectively. Both materials exhibit high strenght and are relatively free-draining, typical of granular materials. The fly ash could be used as an admixture in the stabilization of soft soil. The clay samples treated with fly ash show substantially improved shear strengths and lower compressive properties.

Full Text: 1991\J Env Eng-ASCE117, 320.pdf

Abstract: The homogeneous surface diffusion model (HSDM) has been used extensively to model the dynamics of adsorption of organic compounds onto porous media in natural and engineered systems. A modified finite-difference solution to the HSDM is developed in this paper for multicomponent adsorption in fixed beds. The primary difference between the algorithm presented here and that advanced previously is the alternate selection and structuring of the adsorbent particle boundary conditions. The resulting numerical solution addresses the problems of limited stability and computational inefficiency of the original finite-difference scheme as illustrated in one-, two-, and five-component sample simulations. Comparative sensitivity testing with respect to space and time-step sizes also demonstrates a more clearly defined convergence for the modified solution. The computational speed and ease with which the algorithm can be adapted to a personal-computer code also make it an attractive option alongside more sophisticated, though powerful, numerical techniques such as orthogonal collocation.

Abstract: Adsorption of cadmium by two powdered activated carbons (PAC) is investigated in single and binary adsorbent systems. Both PACs are effective in removing cadmium from solution. Cadmium adsorption increased with increased solution pH. The surface complex formation (SCF) model, a surface-solution chemical equilibrium model, successfully simulated the individual pH-adsorption edges. Cadmium adsorption decreased with increased cadmium surface loading. This phenomenon was attributed to the surface sites having a range of binding energies. Reflecting this phenomenon, several of the complexation constants decreased with the cadmium/carbon ratio. The SCF model successfully simulated the cadmium surface loading versus soluble cadmium curves for the entire range of cadmium and carbon concentrations studied when the cadmium-carbon complexation constants are modified to account for their variation with the cadmium/carbon ratio. Cadmium adsorption in the binary PAC system was observed to follow ideal behavior. The SCF model, using complexation constants determined from single PAC experiments, successfully predicted cadmium removal from solution.

Abstract: The impact of the presence of molecular oxygen on multicomponent adsorption is evaluated in this study. Adsorption equilibria for binary mixtures of phenol/o-cresol and ternary mixtures of phenol/o-cresol/3-ethylphenol on granular activated carbon (GAC) are determined at 23-degrees-C using three different initial-concentration combinations. Experiments were conducted under conditions where molecular oxygen is present (oxic adsorption) and under conditions where oxygen was excluded from the adsorbate solution and the GAC particles (anoxic adsorption). The ideal adsorbed solution theory, using the Myers equation for correlating the single-solute anoxic isotherms, is found to accurately describe the competitive adsorption behavior of these phenolic mixtures under anoxic conditions. When the Freundlich equation was used to describe the single solute behavior, increased deviations were observed. Poor model predictions for the oxic isotherms arc attributed to the presence of molecular oxygen, which promotes the polymerization of the adsorbates on the surface of GAC.

Abstract: The use of granular activated carbon (GAC) columns to treat lead wastewaters was investigated. Synthetic wastewaters containing Pb (10 or 50 mg/L), acetic acid (0.001 N) or EDTA (1: 0.1 or 1: 1 Pb: EDTA molar ratios) were studied. For lead-only and lead-acetic acid experiments significant quantities [70 to 325 bed volumes (BV)] of wastewater were treated prior to breakthrough (C_e = 0.03C₀); X/M-values were as high as about 30 mgPb/g carbon. For EDTA experiments, C_e was always >0.03C₀. The amount of lead not removed corresponded to the amount that was complexed by EDTA. Column pH is the critical parameter influencing column performance. The increase in effluent Pb concentration corresponded with the decrease in column pH. GAC columns were successfully regenerated using a 1 L ( 8 BV) 0.1 N HNO₃ rinse followed by a 1 L 0.1 N NaOH rinse. Column performance was not adversely affected by regeneration. When the regeneration step was used on virgin carbon, a dramatic improvement in column performance was observed and was attributed to the increase in carbon surface pH (pH  11) and the deposition of OH^- in the pore liquid. Possible removal mechanisms are precipitation of lead on the carbon surface, precipitation in the pore liquid and adsorption (surface complexation).

Abstract: A study of biological filtration on granular activated carbon (GAC) has been performed at the Neuilly-sur-Marne (France) treatment plant using experimental pilot filters. Bacterial colonization of GAC was monitored in three carbon filters having varying depths and filtration velocities, but similar empty bed contact time (EBCT). About three months were required to colonize the GAC in the filters and a steady state bacterial biomass of around 2 gC/cm³ GAC was reached. During the colonization period, removal of nonbiodegradable organic carbon (NBDOC) by filtration decreased from 50% to less than 10% showing a gradual saturation of GAC adsorption capacity. However, biological processes take turn with adsorption to ensure a significant removal of biodegradable dissolved organic carbon (BDOC) during the study period (more than 200 days). Filters operating under different conditions did not show any difference in the BDOC removal. This indicates that biological removal of organic matter in GAC filters having a given EBCT is independent of filtration rate (in the range 6 m/h-18 m/h). The maximum bacterial density in the filter effluent water was 1.5×10⁵ bacteria/mL during the colonization phase; this seemed to be linked to a lag in establishing a protozoan population, which, at equilibrium, efficiently removed bacterial biomass produced within the filters. Once established, the efficiency of this complex microbial assemblage was remarkable; the removal of about 0.25 mgC/L of BDOC resulted in the release of less than 0.5×10⁵ bacteria per millileter, around 0.0015 mgC/L as bacterial biomass in effluent.
