摘　　要：用 PSD-CH_2Cl 树脂和 APDC(吡咯烷二硫代甲酸铵)溶液制成一种带有 APDC 功能基的浸渍树脂。研究了Mn、Fe、Co、Ni、Cu、Zn 离子在 APDC 树脂柱上的吸附和解吸特性,并测定了 pH、流速等预富集的最佳条件和外加离子的影响。建立了 APDC 树脂分离、富集、PIXE 法测定天然水中 Mn、Fe、Co、Ni、Cu、Zn 的一种新方法。A SIR(solvent impregnated resin) bearing APDC as a functional group was prepared con- veniently by stirring a solution of APDC with PSD-CH_2Cl resin. The sorption and desorption behaviour of Mn,Co,Fe,Ni,Cu and Zn ions onto APDC resin by column method was studied and the optimum conditions for preconcentration were determined for pH,flow rate and foreign ions in the medium.A new nethod to determine Mn, Fe,Co,Ni,Cu and Zn in natural water by APDC resin preconcentration-PIXE was es- tablished.
