Zn^(2+)在电解还原铕(Ⅲ)过程中的催化行为研究

Study on the Catalytical Action of Zinc(Ⅱ) Ion in the Electrolytic Reduction of Europium(Ⅲ)

本文报道微量Zn^(2+)在电解还原铕(Ⅲ)离子过程中的催化作用,研究结果表明:当阴极中含Zn^(2+)时,铕(Ⅲ)离子将缩短到达定量还原的时间,用循环伏安法监控电极过程的结果表明:电极过程是准一级的催化过程。

In the paper, we report the catalytical action of zinc ion in the electrolytic reduction of europium(Ⅲ). The result shows that when trace zinc ion contained, europium(Ⅲ) in the catholyte will quickly attain quantitative reduction. Cyclovoltammetry graph shows that the electrode process is a pseudo first-order catalytical reaction.
