| 摘 要： | 金属离子在载体作用下在水/有机相界面的传输机制各异,Koryta、Freiser和Senda等人通过研究分别提出了EC、CE及E机制。本文用循环伏安法(CV)对2.2′-联吡啶在水/硝基苯界面电萃取Ni(Ⅱ)的过程进行了研究,结果表明不同条件下萃取过程分别为C_wEC_0,C_wE和C_0E机制。

| Abstract: | Transfer behavior of nickle ion extracted electrochemically by 2,2′-bipyridine at the water/nitrobenzene interface has been investigated by cyclic voitammetry. The preceding or following chemical reaction was coupied to the electrolytic transfer process,respectively. The extracted species are successive complexes between Ni(Ⅱ) and 2,2′-bipyridine An irreversible phenomenon similar to that observed at the metal electrode/electrolyte solution interface was observed directly. Voltam metric behaviors with coupled chemical reactions have been discussed. |
