- Abstract:
- Abstract The possibility of heavy metal (Cu2+) treatment using Saccharomyces cerevisiae and the
effects of the operational conditions on the treatment were studied. The results showed when ρ
(Cu2+) ranged between 20～400 mg/L and the specific biosorption was 2. 98～12. 03 mg/g, Cu2+
treatment by Saccharomyces cerevisiae was feasible. The main removal mechanism was biosorption
process. The biosorption equilibrium was achieved within 10～20 minutes. The optimum temperature
was 15～20℃ and optimum pH ranged between 4. 0～6. 0. The analyses of Freundlich adsorption
equation indicated that η was mainly related with the kinds of heavy metals, and k was related
with the species of yeast and the kinds of heavy metals.
