Abstract

In this paper,Cu~(2+) are adsorbed by a biosorbent,Saccharomyces cerevisiae cultured in laboratory.The results show that the Cu~(2+) biosorption by saccharomyces cerevisiae is a quick process and the optimum pH is 4.It is indicated that Langmuir isotherm sorption model is best in three isotherm sorption models.Furthermore,the biomass also can affect biosorption effect,and the economical ratio of biomass concentration and Cu~(2+) concentration is 100∶1 approximately.
