本文采用新极谱法, 包括半积分, 半微分, 1.5次微分及2.5次微分新极谱研究了四甲铵离子在水/硝基苯界面的传输, 从理论上讨论了峰高, 峰电位及峰宽对传输质点浓度, 扫描速率等因系的依赖关系, 用模拟电子线路在实验上对离子在两相界面传输的新极谱法理论进行了验证, 实验与理论接近, 得到了与金属电极/电解质溶液界面的氧化还原类似的结果.

The transfer behavior of Me4N+ across the H2O-nitrobenzene interface was investigated by polarog., including semiintegral (m), semidifferential (e), 1.5th-order differential (e') and 2.5th-order differential (e'') methods. The predicted dependencies of peak height, peak potential, and peak widthon the concentration and scan rate, etc. are discussed theor. The polarog. theory on the transfer of ions across the interface was experimental confirmed. This method can be used for determing Me4N+.
