摘　　要：通过实验对巯基苯骈噻唑-聚氨酯泡沫塑料(MBT-PF)分离富集微量元素的规律性和机理进行了研究,认为属于沉淀吸附;同时对水样中痕量金和银进行了富集和测定,得到了定量回收。The mechanism of the preconcentration and separation of trace metals fromaqueous soulutious with 2-mercapte-benzothiazole polyurthane foam have been investigated.Theexperiment indicates that the preconcentration is due to precipitation adsorption.THe trace amounts of gold and silver in aqueous solutious have been determined with theresult of high recovery.
