Study on the ph effect of metal solution and biosorbent concentration on cooper (Cu) removal by Saccharomyces.cerevisie from simulated waste water

The production of heavy metals has increased rapidly since the industrial revolution. Heavy metals usually form compounds that can be toxic even in very low concentrations. The conventional methods of removing metals from wastewaters such as chemical precipitation, chemical oxidation or reduction, i...

The level of copper (II) accumulation depends on the pH and initial biomass concentration. Optimum pH values for maximum copper (II) accumulation were determined in range of 3.0-8.0, while effects of concentration on biosorption were in the range 5.0-20.0 mg/ml of the biomass.
