Abstract :
In this study, biosorption of Cu and Mn ions from Sarcheshme copper mine wastewater by locally availableyeast, Saccharomyces Sp., was investigated in batch mode. Optimum amounts for various parameters such ascontact time, pH, initial ion concentration, biosorbent dosage and temperature were determined. Optimum pHwas determined to be 6. Equilibrium was achieved after 120 minutes and no uptake occurred after that.The experimental sorption data was fitted well to the Freundlich adsorption model but there was not acceptablefitness between Langmuir model and experimental data. Also metal ion uptake was increased as the temperatureincreased showing that this experiment was an endothermic process.
