土壤和沉积物中元素的化学形态及其顺序提取法

Chemical speciation of elements in sediments and soils and their sequential extraction process

摘要: 介绍了形态分析的概念和化学形态分析方法,探讨了广泛应用于土壤、沉积物重金属形态分析中的Tessier和BCR顺序提取方案及其异同,综述了顺序提取方法在地球化学、环境科学、农业科学等方面的应用及中国相关标准物质的研制现状。

Abstract: The article introduces the basic concept and analytical technique for chemical speciation and discusses the BCR and Tessier sequential extraction processes applied widely in the chemical speciation of heavy metals in sediments and soils and their difference. Moreover,it also deals with applications of the sequential extraction process in geochemistry,environmental science and agricultural science and the present state of development of relevant reference materials in China.
