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.
