| Abstract: | Beer yeast was used for biosorption which was immobilized by alginate and PVA.The factors including pH,concentration of heavy metal ions,concentration of yeast,time of adsorption,and temperature of adsorption,which could influence the adsorptive capacity for Pb2+,Cu2+,Zn2+andCd2+,were studied.The factors including chemical reagent of desorption and its concentration,which could influence the desorptive capacity for Pb2+,Cu2+,Zn2+ and Cd2+,were studied,too.The result showed that,when the pH was 5.5,the conce... |
