摘要
The kinetics of the tetraethylammonium ion (TEA(+)) transfer at the microhole supported water (w)/o-nitrophenyloctyl ether (NPOE) interface were investigated using steady state voltammetry. Methods proposed in the literature for the determination of quasi-reversible kinetics at metallic microelectrodes were considered. These methods are based on a comparison of the reversible system with the experimental system as the size of the electrode is varied. This approach was found to be unsuitable for the case of ion transfer at the micro w/NPOE interface. (C) 1997 Elsevier Science S.A.
