摘    要:通过培养实验研究了稀土La及其配合物La(POA)3(HPOA=苯氧乙酸)对铅、镉毒害小萝卜的影响,结果表明外加稀土或稀土配合物对铅、镉有明显的解毒作用。用逐步提取法研究萝卜根、茎叶内重金属存在的化学形态,实验表明稀土配合物处理对铅镉主要存在形态影响不大。

关 键 词:  稀土配合物  重金属污染      解毒作用  存在形态  生态防御  解毒机理

Abstract:The effect of rare earth La and its complex La(POA) 3(HPOA=phonoxyactive acid) on raddish under the stress of Pb and Cd was studied by hydroponic experiment.The results showed that rare earth and its complex had obvious detoxication to Pb and Cd.With the studies of heavy metal form using sequential extraction,it showed that treatment of La(POA) 3 had not much effect on dominant sequence of different Pb or Cd form.
Keywords:Pb  Cd  rare earth  rare earth mixture  analysis of different forms on raddish
