铈及其络合物在HPLC色谱柱上保留行为的研究——以离子交换树脂作固定相

Retention Behavior of Cerium and Its Complexes on HPLC Column——Ion Exchange Resin as Stationary Phase

用高效液相色谱(HPLC)与等离子体质谱(ICP-MS)联用技术为分析手段,对铈及其络合物(铈-EDTA,铈-柠檬酸,铈-腐殖酸)在不同固定相上(阳离子交换树脂、阴离子交换树脂)的保留行为及规律性进行了探讨,所得实验结果为稀土形态分析研究提供了有益的依据。

The retention behavior of Ce and its complexes on different stationary phase(cation exchange resin and anion exchange resin) was studied by HPLC-ICP-MS hyphenated technique,and the experimental data provide useful information for the speciation analysis of rare earth elements.
