摘　　要：本文综述了国内外对颗粒物质中金属形态逐级提取测定技术方面的研究情况，重点阐述了颗粒物质金属形态分离方法，并对各相态的浸取技术和金属总量提取方法进行了讨论．从而为开展颗粒物质的金属化学形态的分析和研究，提出几点认识．The present paper concerns the sepuential extraction technique on trace metals in particu late. sample collection and storage at home and abroad. The residual state and total amount digestion have also been discussed. For further detecting content of the chemical form in sediments of water and suspended particulate some approaches from the experiment and research in theory are examined.
