【摘要】 用 PSD-CH₂Cl 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。更多还原

【Abstract】 A SIR（solvent impregnated resin） bearingAPDC as a functional group was prepared con-veniently by stirring a solution of APDC withPSD-CH₂Cl resin.The sorption and desorption behaviour ofMn,Co,Fe,Ni,Cu and Zn ions onto APDCresin by column method was studied and theoptimum conditions for preconcentration weredetermined for pH,flow rate and foreign ionsin the medium.A new nethod to determine Mn,Fe,Co,Ni,Cu and Zn in natural water byAPDC resin preconcentration-PIXE was es-tablished.更多还原
