用循环伏安法研究了百里香酚兰在水 /硝基苯界面的离子转移行为。根据百里香酚兰在溶液中的离解平衡和电化学性质 ,讨论了界面离子转移机理 ,并计算了转移离子的标准转移电位△ W0 φ0 和标准吉布斯转移能△ W0 G0 。实验所测半波电位△ W0 φ1 /2 —pH曲线与理论公式相符
Cyclic voltammetry was used to study the ion transfer behavior of thymol blue at the water / nitrobenzene interface. Based on the dissociation equilibrium and electrochemical properties of thymol blue in solution, the interface ion transfer mechanism was discussed and the standard transfer potential △ W0 φ0 and the standard Gibbs transfer energy △ W0 G0 were calculated. The measured half-wave potential △ W0 φ1 / 2 -pH curve consistent with the theoretical formula
