百里香酚兰的液液界面离子转移过程

ION TRANSFER OF TPB ACROSS THE LIQUID/LIQUID INTERFACE

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 ΔWOφ0 和标准吉布斯转移能 ΔWOG0 。实验所测半波电位 ΔWOφ1 /2 - p

The ion transferof TPB acrosstheinterface of W/ NB was studied by cyclic voltammetry.The transfer mechanism of TPB was proposed in terms of its electro- chemical behavior and equilibria of dissociation.The experimental data obtained for half- wave potentialΔWOφ1 /2 and p H in W phase was in agreementwith the theoretical e- quation.The standard potential differencesΔWOφ0 and standard Gibbs energy of TPB across the interface were calculated.
