摘要
本文报导以Er(PMBP)_3和Pr(PMBP)_3为敏感活性物质的PVC液膜离子选择性电极的制奋、电极性能及其在稀土定量分析中的初步应用。研究结果表明:上述电极具有响应快、稳定性好和寿命较长等优点,并且在对稀土离子Re^(3+)的定量分析中有一定的准确性。
In the paper, authors reported the preparation and function of rare earth ion-selective electrodes with rare earth active material-containing PVC membrane, and the application of the electrodes in the analysis of rare earth elements. The result showed: the electrodes bear good characteristics such as quick response, stability, durability and considerable accuracy in quantative analysis of rare earth.
