| 摘 要： | 采用AGMP-1阴离子交换树脂，分别以7mol／L HCl、2mol／L HCl、0．5mol／L HNO3作为淋洗剂，可有效分离Cu、Fe、Zn。介绍了方法的基本原理、化学分离过程及混合标准溶液与地质标样的分离结果。结果表明，Cu、Fe、Zn回收率均接近100％，标准溶液在离子交换分离前后同位素组成一致，可以满足多接收器等离子体质谱对Cu、Fe、Zn同位素高精度分析的要求。

| Abstract: | Complete separation of Cu, Fe and Zn in geological samples has been achieved using anion exchange chromatography. AG MP-1 resin was used as anion exchange resin and 7 mol/L HCl, 2 mol/L HCl and 0. 5 mol/L HNO3 were used as eluants. The basic principle and chemical separation process of the method, the separation results of multi-element standard solutions and geological standard samples have been discussed in some details. Results show that the recoveries for Cu, Fe and Zn are all close to 100% without introducing mass fractionation during the separation, which satisfy high-precision measurements of Cu, Fe and Zn isotooe ratios using MC-ICPMS. |
