摘要
研究了稀土元素Ce4+对铜绿微囊藻生长效应及其被铜绿微囊藻富集的动力学过程。结果表明:当Ce4+的添加浓度小于0.2mg/L时,对铜绿微囊藻的生长有促进作用,当Ce4+的添加浓度大于0.2mg/L时铜绿微囊藻的生长受到抑制。Ce4+在铜绿微囊藻中富集的动力学过程可用二级吸附动力学模型表征。
This paper studies the kinetics of cerium,one of rare earth elements regarding its effect on growth of Microcystis aerugenosa and its being enriched by Microcystis aerugenosa. The results show that addition of Ce^(4+) to the concentration under 0.2 mg/L would accelerate growth of Microcystis aerugenosa; more than that would inhibit the growth. The paper concludes the accumulation and enrichment of Ce^(4+) in Microcystis aerugenosa follows second- order kinetics adsorption model.
