| 摘 要： | 在静态供试水体中分别添加不同浓度的Ce(IV),利用定期测定水体中N、P、DO、COD含量及藻类叶绿素水平的方法,研究Ce对富营养化水体中浮萍藻类增长的影响.结果表明,在本实验条件下,添加较低浓度Ce(0.15,0.25,0.50 mg/L)能促进红浮萍生长和实验水体的富营养化,但随着浓度的进一步升高(1.0 mg/L),则对红浮萍生长和实验水体的富营养化有抑制作用.

| Abstract: | The different concentrations of Ce were added to a static system of experimental water separately,and the contents of N,P,DO,COD and alga chlorophyll level in the water body were determined regularly.The influence of Ce on the growth of red duckweed in eutrophic water was investigated in this paper.The results reveal that,under this experimental condition,adding low concentrations of Ce(0.15,0.25,0.50 mg/L) can promote growth of red duckweed and eutrophication of experimental water.With further rising of the concentration(1.0 mg/L),the growth of red duckweed and eutrophication of experimental water will be restrained. |
