摘　　要：二硫代氨基甲酸盐 (dithiocarbamate ,DTC)衍生物对重金属有极强的螯合能力 ,在环境治理中主要有螯合剂和螯合树脂两种利用形式。前者主要用于成分复杂污染物中重金属离子的去除 ;后者主要用于环境分析中金属的分离与预富集。今后进一步研究方向应为 :根据物质结构与性能的关系 ,开发更加稳定、高效、低毒的产品 。Dithiocarbamate (DTC) derivatives have a strong ability of chelating heavy metals, which are used in environmental treatment mainly in forms chelating agent and chelating resin. The former is mainly used to remove heavy metal ions in the complicated contaminants; the latter is mainly used to separate and pre-concentrate metals in environmental analysis. In the future, further investigation should be made to develop more stable, effective and less toxic products according to the relation between their structures and performances, and more attention should be paid to researches on their application processes.
