Abstract: The frontier orbital energies of montmorillonite molecule and [Me (H₂O)₆]²⁺ (Me = Cu²⁺, Zn²⁺, Co²⁺ and Ni²⁺) were calculated by INDO method. Results showed that the chemical interaction between montmorillonite molecule and [CU (H₂O)₆]²⁺ or [Zn (H₂O)₆]²⁺ was possible. The experimental results of powder X-ray diffraction and isothermal adsorption supported the above-mentioned calculation results.

Abstract: It was discovered that the adsorption of metal ions on mineral surface had much to do with their activation for mineral in flotation. The authors proposed a percentage of adsorptive precipitation (PAP) to represent activation power of metal ions. The greater the PAP of the metal ion, the stronger its activation power. When the PAP was small to a certain extent, the metal ion showed a depression effect on mineral in flotation.

Abstract: To study the effect of pH on Cd adsorption and species, the red soil was taken as adsorbent. The curve of Cd adsorbed vs pH shows three stages, namely, the adsorption amount increasing slowly at low pH, then increasing quickly with the rise of pH, and reaching the maximum amount at high pH. The result of theoretical analysis on precipitation reactions indicates that the precipitation reaction is controlled by carbonate until pH is a bit higher than 11. The adsorption data at different pH values and initial Cd(R) concentrations were fitted by a linear least squares technique, to the Langmuir, Frundlich and Temkin adsorption isotherms, and the results show that Langmuir isotherm is the best which can well describe the adsorption behavior of Cd in red soil. At last, a pH-dependent model of adsorption isotherms of Cd was established by substituting the fitting results obtained from experimental data for the parameters in Langmuir equation.

Abstract: The potential of living Aspergillus niger to remove cadmium and zinc from aqueous solution was investigated. Effects of pH, initial concentration, contact time, temperature and agitation rate on the biosorption of Cd(II) and Zn(II) ions were studied. The optimum adsorption pH value for Cd(II) and Zn(II) were 4.0 and 6.0. The best temperature and agitation rate were in the range of 25-30°C and 120 r/min for all metal ions. Under the optimal conditions, the maximum uptake capacities of Cd(II) and Zn(II) ions are 15.50 mg/g and 23.70 mg/g at initial concentrations of 75 mg/L and 150 mg/L, respectively. Biosorption equilibrium is established within 24 h for cadmium and zinc ions. The adsorption data provide an excellent fit to Langmuir isotherm model. The results of the kinetic studies show that the rate of adsorption follows the pseudo-second order kinetics.

Abstract: Adsorption of silver ions from aqueous solution onto H₂TiO₃ was studied. Equilibrium experimental studies were performed to determine the adsorption capacity of H₂TiO₃ for silver ion at various pH values. Batch experiments were conducted in the range of pH value 3-7 and silver ions concentration 10-200 mg/L. The results show that the adsorption is strongly dependent on pH value. The equilibrium absorption capacity of H₂TiO₃ increases significantly with the increase of pH value from 3 to 7. The adsorption of silver ion obeys the Langmuir isothermal equation well in the concentration range studied, the adsorption constant is 0.054 7, 0.052 4, 0.088 1 at pH 5, 6 and 7, respectively, and the maximum adsorption capacities are 23.64, 29.76 and 40.82 mg/g.

Abstract: A novel sorbent, bio-formulation(BF), was prepared and employed for the adsorption of cadmium(Cd) ion from. aqueous system. The process of adsorption follows the pseudo second-order kinetic equation and the adsorption behavior is fitted with a Freundlich isotherm. The removal rate of Cd is slightly dependent on the initial pH value over a wide range of 4-11. The addition of Zn²⁺ and Cu²⁺ ions hardly affects the Cd adsorption, whereas the coexisting Pb²⁺ ion greatly interferes with the adsorption. The adsorption mechanism is supposed as a cation-exchange process between Cd²⁺ and calcium and Mg²⁺ present on the surface of BF, and somewhat as adsorption in a hydrolyzed form. The adsorbed Cd ions are desorbed effectively by a 0. 1 mol/L HCl solution.

Abstract: Four chromium(VI)-resistant bacteria named YB-1, YB-2, YB-3 and YB-4 were isolated from Cr-electroplating sludge. YB-1 and YB-2 were identified as a member of Bacillus sp. based on morphology and Biolog Microstation System. The strain of YB-1 was selected to test for its resistance and ability to remove Cr(VI) from aqueous solution. The results indicate that YB-1 exhibits high MIC value which can almost reach 140 mg/L and the growth of YB-1 in liquid medium containing 60 mg/L Cr(VI) is affected especially in the late exponential phase and stationary phase. Furthermore, the potential of living and freeze-dried YB-1 biomass to remove Cr(VI) was studied in different pH, biosorbent dose, contact time and initial concentration using the batch method. At the optimal conditions, living and freeze-dried biomass are capable of absorbing 34.5 mg/g and 17.8 mg/g chromium(VI) at initial concentration of 60 mg/L, respectively. The adsorption data were fitted to Langmuir isotherm model for these two sorbents. Kinetic studies show that the rates of sorption all follow the pseudo-second order kinetics.

Abstract: Cu(II) biosorption by orange peel that was chemically modified with sodium hydroxide and calcium chloride was investigated. The effects of temperature, contact time, initial concentration of metal ions and pH on the biosorption of Cu(II) ions were assessed. Thermodynamic parameters including change of free energy (ΔG°), enthalpy (ΔH°) and entropy (ΔS°) during the biosorption were determined. The results show that the biosorption process of Cu(II) ions by chemically treated orange peel is feasible, spontaneous and exothermic under studied conditions. Equilibrium is well described by Langmuir equation with the maximum biosorption capacity(q_m) for Cu(II) as 72.73 mg/g and kinetics is found to fit pseudo-second order type biosorption kinetics. As the temperature increases from 16ºC to 60ºC, copper biosorption decreases. The loaded biosorbent is regenerated using HCl solution for repeatedly use for five times with little loss of biosorption capacity.

Abstract: The adsorption of biopesticide avermectins onto activated carbon from ethanol solution with different initial concentrations at 303.15 K was performed. The obtained equilibrium and kinetic data of the adsorption process were assayed to evaluate the adsorption potential of activated carbon for avermectins. The results show that the activated carbon is effective for the adsorption of avermectins. Moreover, the adsorption of avermectins onto activated carbon agrees with Langmuir isotherm model, while pseudo-second-order kinetics model is better fitable for such adsorption process. In addition, activated carbon can efficiently protect adsorbed avermectins from photodegradation.

Abstract: Copper adsorption by orange peel, which was chemically modified with sodium hydroxide, was investigated. The adsorbent was characterized using surface area analyzer, infrared spectroscopy and scanning electron microscopy. Total negative charge and zeta potentials on the adsorbent surface were determined. Equilibrium isotherms and kinetics were obtained and the effects of solution pH value, adsorbent concentration and temperature were studied in batch experiments. Column experiments were performed to study practical applicability, and breakthrough curves were obtained. Equilibrium is well described by Langmuir and Freundlich isotherms, and kinetics is found to fit pseudo-second order type adsorption kinetics. According to Langmuir equation, the maximum adsorption capacity for Cu(II) is 50.25 mg/g at pH value of 5.3. The results show additional chemical modification of the adsorbent by NaOH and the increased adsorption capacity.

Abstract: SP-C was applied for the removal of Cu²⁺ from simulated cobalt sulfate electrolyte containing Co²⁺ 50 g/L and Cu²⁺ 0.5-2.0 g/L. Experimental conditions included pH of 2-4, temperature of 20-60ºC and contact time of 10-40 min. The investigation demonstrated that SP-C had recommendable efficiency in adsorbing Cu²⁺ from the electrolyte with 25- to 100-fold of Co²⁺. The optimal adsorption conditions of SP-C were pH of 4, contact time of 30 min and ambient temperature. The study also showed that the loaded resin could be effectively eluted with 2.0 mol/L H₂SO₄ solution at a contact time of 40 min; the peak concentration of Cu²⁺ in the eluate was about 35 g/L. The sorption characteristics of Cu²⁺ by SP-C could be described by Langmuir isotherm and the pseudo second-order kinetic equation. Infrared spectra showed that nitrogen atoms in the functional group coordinated with Cu2+ to form coordination bands.

Abstract: Adsorption and desorption behavior of Yb(III) by SQD-85 resin was investigated by various chemical methods and IR spectrometry. The adsorption capacity of SQD-85 resin for Yb(III) was studied as a function of solution pH, initial concentration of Yb(III), temperature and contact time. The optimal pH for the adsorption was 5.50 in the HAc-NaAc system, and the maximum adsorption capacity was estimated to be 347.6 mg/g at 308 K. The isotherms adsorption data fit well with Langmuir model. The adsorption kinetics data are in agreement with pseudo-second-order model. Thermodynamic parameters indicate that Yb(III) adsorption by SQD-85 resin is endothermic and spontaneous in nature. Thomas model is reasonably accurate in predicting experimental column results. The dynamic desorption rate of Yb(III) can increase to 97.3% when the elution agent is 1.0 mol/L HCl. These results suggest that Yb(III) in aqueous solution can be removed and recovered by SQD-85 resin efficiently.
