不同提取剂对蔗田土壤中重金属有效态提取效率的研究
采用4种提取剂提取广西某受重金属污染的蔗田土壤中有效态Cu、Zn、Pb和Cd。结果表明:各提取剂对土壤有效态Cu、Zn、Pb和Cd的提取量顺序为HNO3〉HOAc〉Ca Cl2〉Na NO3;土壤重金属Cu、Zn、Pb、Cd任意两个元素的提取率间呈现极显著的相关性。...

The results showed that the sequence of four extractants according to the extraction contents of available Ca, Zn, Pb and Cd in the soil was HNO3〉HOAc〉CaC12〉NaNO3. There was a very significant correlation between the extraction rates of any two elements among Cu, Zn, Pb and Cd. |
