利用改进的BCR法和Tessier法提取稻田土壤中Pb、Cd的对比研究
Comparative St udy on Extractiono f Pb and Cd from Paddy Soils by Modified BCR Metho d and Tessier Method
摘要
Abstract
Abstar ct: The author respectively used modified BCR method and Tessier method to determine and analyze the contents of various forms of heavy metal elements Pb and Cd in paddy soil samples in Gejiu city of Yunnan province .The results showed that:in soil samples, Cd existed mainly in the form of acid-extractable state, and Pb existed mainly in the form of reducible state;the modified BCR method possessed a higher accuracy in analysis than Tessier method;the effective-state content of heavy metals in soil obtained by Tessier method was higher than that did by modified BCR method;there were very significant correlations between the contents of some forms of heavy metals in soil measured by these two methods .关键词
