HQS螯合负载聚氨酯泡沫塑料在分离富集痕量金属中的应用

Application of Polyamine Lather Chelating Loaded HQS in Separation and Enrichment of Trace Metal Ions

8 羟基喹啉 5磺酸 (HQS)螯合负载泡沫塑料制备容易 ,可用于痕量元素的分离富集 .与相应的离子交换树脂相比 ,该负载泡塑具有交换速率快 ,易洗脱等特点 .本文提出采用HQS螯合负载泡塑富集 -原子吸收光谱测定天然水中痕量Pb ,Cd ,Cu ,Ni等元素的分析方法 .

Polyamine lather chelating loaded HQS is prepared easily and can be applied in separation and enrichment of trace metal ions.compared with exchange resin,loaded lather is characteristic of high exchange speed and easy elution.The method is suggsted in this paper that with enrichment of HQS loading polyamine lather Pb,Cd,Cu,Ni are determined by AAS.The precision and accuracy are good.
