摘要
近年来许多电化学方法已用于油/水界面研究中,如循环伏安法、计时电位法、循环线性扫描电流极诸法、滴电解质极谱法和扫描电流极谱法、交流阻抗和交流循环伏安法。本文采用新极谱法,包括半积分、半微分、1.5次微分及2.5次微分新极谱法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、扫描速率等因素的依赖关系。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,得到了与在金属电极/电解质溶液界面的氧化还原类似的结果。
The transfer behavior of tetramethylammonium cation (TMA^+) across the water/
nitrobenzene interface has been investigated by neopolarography including
semiintegral (m), semidifferential (e), 1.5th order differential (e′) and 2.5 th order
differential (e″) methods. The predicted dependences of peak height, peak potential and
peak width on concentration and scan rate, etc have been discussed theoretically. The
neopolarographic theory on the transfer of ions across the interface has been confirmed
experimentally.
