摘要
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。
Four kinds of extractants were chosen to extract the available Cu, Zn, Pb and Cd from the soil of a heavy-metal- polluted sugarcane field in Guangxi. 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.
