| 中文摘要 | In the paper the kinetic effects of La3+ and Ce4+ on the growth of Microcystis and the accumulation kinetics of Microcystis in the single and combined systems of La3+ and Ce4+ were studied. The mechanism of the effects of La3+ and Ce4+ on the growth of Microcystis and their accumulation kinetics were also discussed. In the single system, La3+ stimulated the growth of Microcystis at initial concentrations below 2 mg / 1, but inhibited it above 2 mg / 1. Ce4+ accelerated the growth of Microcystis at initial concentrations below 0.2 mg / 1 and inhibited at above 0.2 mg /l. Furthermore, the stimulation weakened with the increase of initial concentrations of La3+ and Ce4+. In the combined system, the growth of Microcystis was accelerated in the over all cases. In the single system, the amount of La3+ and Ce4+ uptake was more at higher initial concentrations than at lower ones. At the same initial concentrations, La3+ and Ce4+ uptake in the combined system was less than that in the single system. The kinetic process of La3+ and Ce4+ adsorpted by Microcystis can be explained with the second order kinetics adsorption model. |
