Abstract: Bagasse pith (BP) has been utilized for activated carbon preparation using H3PO4 (BPH) or KOH (BPK) as a chemical activating agent followed by carbonization at 500 C. The physicochemical properties of activated carbon were carried out. The effectiveness of carbon prepared in adsorption of Rhodamine B (RhB) has been studied as a function of adsorbent type, pH, particle size, agitation time, temperature, initial dye concentration, and desorption. The results obtained showed that the adsorb ability of (RhB) to the BPH is higher than that of the BPK carbon by approximately 10 folds (198.6 and 21.5 mg g^-1. respectively). Kinetic studies show that the adsorption of RhB proceeds according to the pseudo-second-order. The intra-particle diffusion was identified to be the rate-limiting step in addition to the film diffusion. The adsorption was analyzed using 5 isotherm models (Langmuir, Freundlich, Temkin, Harkins-Jura, and Halsey isotherm equations). The highest values of r² were obtained with Langmuir (0.997). The adsorption capacity, q_m, was 263.85 (mg g^-1) at initial pH 5.7 for the particle size 0.25 nm and equilibrium time of 240 min at a temperature of 20°C and initial dye concentration range of 100-600 (mgl^-1). Temperature effect proves that the adsorption is endothermic with ΔH = 4.151 (kJ mol^-1), ΔS = 65.786 (J mol^-1 K^-1) and a decrease in Gibbs energy (ΔG = -7.939 to -26.729 kJ mol^-1). Desorption studies Were carried out using water medium, HCl and NaOH with desorption of 2.7, 5.4 and 7.8%, respectively of adsorbed RhB confirming the chemical adsorption mechanism of the dye. This adsorbent was found to be both effective and economically viable. Crown Copyright (C) 2009 Published by Elsevier B.V. All rights reserved.

Abstract: The present study investigates the adsorption potential of Punica granatum (pomegranate) peel as an adsorbent for the removal of 2,4-dichlorophenol (2,4-DCP) from aqueous solutions The adsortipon was studied as a function of contact time, initial concentration and temperature by batch method The adsorption capacity of pomegranate peel adsorbent for 2,4-DCP was found to be 65.7 mg g^-1. The equilibrium adsorption data was well described by the Langmuir model. Kinetic studies suggest that the present system of phenol adsorption on pomegranate peel adsorbent could be described more favorably by pseudo-first-order kinetic model. Column studies were also undertaken in order to rest the practical utility of prepared adsorbent and found promising. After the adsorption studies, the phenol-laden adsorbent was stabilized in cement for its ultimate disposal. The results of the present Study clearly reveal that prepared adsorbent can be used beneficially in treating industrial effluents containing phenols and safely disposed of by stabilizing into cement.

Abstract: Using a redox process, granular activated carbon (GAC) was coated with manganese oxides to enhance its ability to adsorb fluoride from an aqueous solution. Compared with plain GAC, the fluoride adsorption capacity of this new adsorbent was improved and at least three times greater than that of uncoated GAC. The surface characteristics of coated GAC were observed with scanning electron microscopy. The surface area of the new adsorbent was calculated using the Brunauer-Emmett-Teller method. X-ray diffraction revealed that manganese oxides are amorphous. X-ray photoelectron spectroscopy demonstrated that manganese existed primarily in the oxidation state +IV. Kinetic and equilibrium adsorption data showed that the adsorption process follows the pseudo-second order kinetic and Freundlich equation models, The sorption data also indicated that the removal of fluoride by adsorption is a highly complex process, involving both boundary layer diffusion and intra-particle diffusion. The pH value of solution influences fluoride removal. and the optimum equilibrium pH value of fluoride adsorption is 3.0. (C) 2009 Elsevier B.V. All rights reserved.

Abstract: In this study, poly (methacrylic acid) modified biomass was prepared to improve the adsorption capacities for three dyes: methylene blue (MB), rhodamine B (RB) and basic magenta (BM). FTIR and potentiometric titration demonstrated that a large number of carboxyl groups were introduced on the biomass surface, and the concentration of the functional group was calculated to be 1.4 mmol g^-1 by using the first and second derivative method. According to the Langmuir equation, the maximum uptake capacities (q(m)) for MB, RB and BM were 869.6, 2674 and 719.4 mg g^-1, which were 17-, 11- and 12-fold of that obtained on the unmodified biomass, respectively. Adsorption kinetics study showed that the completion of the adsorption process needed only 70 min, which is faster than that occur with the common sorbent Such as activated carbon and resin. Temperature and ionic strength experiment showed that they both had effect on the adsorption capacity of the modified biomass. Good result was obtained when the modified biomass was used to treat dye wastewater. (C) 2009 Elsevier B.V. All rights reserved.

Abstract: Biomass of Aeromonas hydrophila was successfully utilized for the removal of lead from aqueous solution. The effect of process variables such as pH, initial Pb(II) concentration, biomass dose and temperature on the uptake of lead were investigated using two level four factor (2(4)) full factorial central composite design with the help of MINITAB (R) version 15 software. The predicted results thus obtained were found to be in good agreement (R-2 = 98.6%) with the results obtained by performing experiments. The multiple regression analysis and analysis of variance (ANOVA) showed that the concentration has positive and temperature and biomass dose have negative whereas pH has curved relationship with the uptake of Pb(II). The maximum uptake of Pb(II) predicted by optimization plots was 122.18 mg/g at 20°C, initial Pb(II) concentration of 259 mg/L, pH 5.0, temperature 20°C and biomass dose 1.0 g. Langmuir isotherm model was applicable to sorption data and sorption capacity was found to be 163.3 mg/g at 30°C, pH 5.0 and Pb(II) concentration range 51.8-259 mg/L indicate that the biosorbent was better in comparison of the biosorbent reported in the literature. Dubinin-Radushkevich (D-R) isotherm model was also applied and it was found that sorption was chemisorption (E = 12.98 kJ/mol). FT-IR studies indicate the involvement of various functional groups present on biomass surface in the sorption of Pb(II). (C) 2009 Elsevier B.V. All rights reserved.

Abstract: The extraction abilities of p-tert-butylcalix[n]arenes (n = 6, 8) and their carboxylic acid and methyl ester derivatives upon some carcinogenic aromatic amines have been investigated. The separation and quantification of aromatic amines were performed by high-performance liquid chromatography with Ace 5 C-18 column and diode array detection. The optimum pH values for aromatic amines sorption were observed at pH 4.0, 7.0 and 8.5 for all calixarene derivatives. In batch sorption experiments of selected carcinogenic aromatic amines, the experimental results show that octacarboxylic acid derivative of p-tert-butylcalix[8]arene exhibited a better affinity than other compounds towards all aromatic amines species at almost all pHs. The sorption of aromatic amines by carboxylic acid derivatives of p-tert-butylcalix[n]arene indicates that carboxyl groups play the major role for the formation of hydrogen bonds and electrostatic interactions between sorbent and aromatic amine.

Abstract: Removal and recovery of aromatic pollutants from water by solid adsorbents have been of considerable concern recently. Relatively limited information is available on desorption kinetics and isotherms aspects. In the present study, batch desorption experiments of loaded 4-nitrophenol on a hyper-cross-linked polymer resin NDA-701, a polymeric adsorbent Amberlite XAD-4 and a granular activated carbon GAC-1 were carried out to study the effects of reaction temperature and pore-size distribution of adsorbents. 4-Nitrophenol desorbed rapidly in the early stages, followed by a much slower release, which was described well by a first-order two-component four-parameter model. The adsorption and desorption equilibrium isotherms were well described by Freundlich equation and the apparent adsorption-desorption hysteresis (hysteresis index) for 4-nitrophenol followed an order as: NDA-701 approximate to XAD-4 << GAC-1. Analysis of adsorption-desorption process suggested that higher reaction temperature and larger proportion of macropore of adsorbents favoured desorption kinetic and reduced adsorption-desorption hysteresis. All the results indicated that NDA-701, with a specific bimodal property in macro- and micropore region, had excellent potential as an adsorption material for achieving high removal and recovery of 4-nitrophenol from the contaminated water. These results will also advance the understanding of the adsorption and desorption behavior of hyper-cross-linked polymer resin in the wastewater treatment systems. (C) 2009 Elsevier B.V.

Abstract: The increased demand for the lanthanides in commercial products result in increased production of lanthanide containing ores, which increases public exposure to the lanthanides, both from various commercial products and from production wastes/effluents. This work investigates lanthanide (La, Ce, Pr, Nd, Eu, Gd and Lu) binding properties of self-assembled monolayers on mesoporous silica supports (SAMMS (TM)), that were functionalized with diphosphonic acid (DiPhos). acetamide phosphonic acid (AcPhos), propionamide phosphonic acid (Prop-Phos), and 1-hydroxy-2-pyridinone (1,2-HOPO), from natural waters (river, ground and sea waters), acid solutions (to mimic certain industrial process streams), and dialysate. The affinity, capacity, and kinetics of the lanthanide sorption, as well as regenerability of SAMMS materials were investigated. Going from the acid side over to the alkaline side, the AcPhos- and DiPhos-SAMMS maintain their outstanding affinity for lanthan ides, which enable the use of the materials in the systems where the pH may fluctuate. In acid solutions, Prop-Phos- and 1,2-HOPO-SAMMS have differing affinity along the lanthanide series, suggesting their use in chromatographic lanthanide separation. Over 95% of 100 mu g/L of Cd in dialysate was removed by the Prop-Phos-SAMMS after 1 min and 99% over 10 min. SAMMS can be regenerated with an acid wash (0.5 M HCI) without losing the binding properties. Thus, they have a great potential to be used as in large-scale treatment of lanthanides, lanthanide separation prior to analytical instruments, and in sorbent dialyzers for treatment of acute lanthanide poisoning.

Abstract: This work investigated the equilibrium batch dynamics of using olive oil mill solid residues as an adsorbent for zinc removal from aqueous solutions. It was found that a sorbent concentration of 4 g L^-1 achieved the best removal percentage and the best sorbent capacity. Adsorption equilibrium was reached in 60 min for an initial zinc concentration of 0.25 mmol/L and 180 min for an initial zinc concentration of 1-3 mmol/L A particle size of olive mill residue ranging from 0.85 to 1.18 mm was used in the study. It was found that the maximum adsorption capacity of zinc was at a pH value of 5.0. It was found that q(max) for zinc ions, was 5.63, 6.46, and 7.11 mg g^-1 at temperature values of 298, 308, and 328 K, respectively. The data pertaining to the sorption dependence upon metal ion concentration could be fitted to a Langmuir isotherm model. The second-order kinetic model provided the best correlation of the data. The change in entropy (S°) and heat of adsorption (H°) for zinc ions adsorption on olive mill solid residues were estimated as -1419 kJ kg^-1 K^-1 and 4.7 kJ kg^-1, respectively. The examined low-cost adsorbent could offer an effective way to decrease zinc ions concentration in wastewater. (C) 2009 Elsevier B.V. All rights reserved.

Abstract: This work reports on the assessment of the dye methylene blue biosorption properties of Pyracantha coccinea berries under different experimental conditions. Equilibrium and kinetic studies were carried out to determine the biosorption capacity and rate constants. The highest biosorption yield was observed at about pH 6.0, while the biosorption capacity of the biomass decreased with decreasing initial pH values. Batch equilibrium data obtained at different temperatures (15, 25, 35 and 45C) were modeled by Freundlich, Langmuir and Dubinin-Radushkevich (D-R) isotherms. Langmuir isotherm model fitted the equilibrium data, at the all studied temperatures, better than the other isotherm models indicating monolayer dye biosorption process. The highest monolayer biosorption capacity was found to be 127.50 mg/g dry biomass at 45C. Kinetic studies indicate that the biosorption process followed the pseudo-second-order model, rather than the pseudo-first-order model. ΔG, ΔH, and ΔS parameters of biosorption show that the process is spontaneous and endothermic in nature. The biosorbent-dye interaction mechanisms were investigated using a combination of Fourier transform infrared spectroscopy and scanning electron microscopy. The biosorption procedure was applied to simulated wastewater including several pollutants. The results obtained indicated that the suggested inexpensive and readily available biomaterial has a good potential for the biosorptive removal of basic dye. (C) 2009 Elsevier B.V.

Abstract: Removal of arsenic from groundwater by biological adsorptive filtration depends largely on its interaction with biogenic iron and manganese oxides surfaces. In the present study we investigated the arsenic adsorption and abiotic oxidation capacities of an aged biofilter medium (BM2) collected from a long time established groundwater treatment plant for removal of iron and manganese by biological filtration. Batch oxidation/adsorption kinetic experiments indicated that BM2 can easily oxidize As(III) to As(V) with the rate of oxidation less affected by pH-variations from 4 to 8.5. The adsorption capacity of the biofilter medium for the produced or added As(V), however, depends strongly on the pH of the solution. The kinetics results have shown that As(Ill) sorption followed pseudo-second order kinetics, whereas the sorption of As(V) was best described by the intra-particle diffusion model, indicating that adsorptions of As(III) and As(V) onto BM2 were governed by different mechanisms. Adsorption isotherms at 25C were measured for a range of arsenite and arsenate initial concentrations of 0.67-20 mu mol/L and the pH range from 4 to 9. Adsorption maxima were highest at pH 4 and decrease steadily as the pH increases. The equilibrium data for both As(III) and As(V) fitted very well to the Freundlich and Sips isotherm equations and, in most cases, the two isotherms overlapped with the same correlation coefficients, indicating sorption to be multilayer on the heterogeneous surface of BM2. The implication of the data for arsenic removal from water by biological filtration has been discussed. (C) 2009 Elsevier B.V. All rights reserved.
