【Abstract】 In this paper,the kinetics process of the effect of rare earth element La 3+ on the growth of microcystis and the accumulation of La 3+ by microcystis were investigated.The results indicates that the growth of microcystis can be stimulated at below 2 mg·l -1 of La 3+,and it was inhibited at above 2 mg·l -1 of La 3+.The kinetics process of accumulation of La 3+ by microcystis can be described by a surface coordination model.更多还原
