摘要： 本文用循环伏安法研究了Re0_4~-L、102、MnO_4~-等过氧酸根阴离子在水/硝基苯界面上的转移过程, 详细研究了各种条件对转移离子行为的影响. 三种离子均表现为可逆离子转移过程。转移过程CV峰电流与水相中阴离子的浓度成线性关系, 据此可进行ReO_4~-、TO_4~-、MnO_4~-的测定, 并且有用液/液界面电化学方法监测IO_4~-的氧化还原反应的意义。

Abstract: The transfer of ReO_4~-, IO_4~- and MnO_4~- anions across the water/nitrobenzene interface was investigated by cyctic voltammetry with four electrode system. The transfer process of these anions is ascribed to the diffusion-controlled under the experimental conditions. The linear relationship between the peak current and concentration of these anions in aqueous phase can be used for analysis and monitoring the chemical reaction between IO_4~- and N (C_2H_4OH)_3.
