本文用四电极循环伏安法研究了非离子型表面活性剂Triton X-100推动碱金属离子K^+, Na^+等在水/硝基苯, 水/1,2-二氯乙烷界面上的转移过程, 根据实验结果提出Triton X-100推动金属离子转移的一种机制, 推导了转移半波电位方程式, 并用实验进行了验证。

The transfer behavior of alkali metal ions K+ and Na+ across the interfaces of water/nitrobenzene and water/1,2-dichloroethane facilitated by Triton X-100 is investigated by cyclic voltammetry with four electrodes. The equations of interfacial half-wave potential derived in terms of the mechanism proposed is verified by the experimental data.
