Abstract

Abstract

The biosorption process of Cu2 +by Saccharomyces cerevisiae was researched. The results showed that the p H,the concentration of Cu2 +,the adsorption time and the amount of Saccharomyces cerevisiae had significant effects on the adsorption of Cu2+. Result showed that the optimal conditions were as follows:the p H4.5,the concentration of Cu2 +38.10 mg/L,adsorption time 150 min,the amount of Saccharomyces cerevisiae0.45 g. Under such an optimal condition,the adsorption rate of Cu2+by Saccharomyces cerevisiae reached at96.2% and the adsorption capacity was 2.44 mg/g.
