摘要: AbstractIn this present study, biosorption of Zn (II) from aqueous solutions by living bacteria Pseudomonas aeruginosa was investigated in batch experiments. The effects pH, bacterial dosage, initial concentration, contact time, and temperature were studied. Removal process influenced significantly the variation biosorbent ion temperature, time. Optimum conditions found to be pH 6, dosage 0.5 g/l, concentration 100 mg/l at room time 90 min. maximum uptake capacity P. for ions 46.1 mg/g optimum conditions. correlation coefficient second-order kinetic model 0.997. Langmuir Freundlich isotherm models also applied equilibrium system data better fitted with isotherm. Finally, adsorption compared other bi...
