摘要：

Ni(Ⅱ)离子可与聚8羟基喹啉、聚邻氨基酚、聚邻苯二胺和聚苯胺络合。聚合物-Ni(Ⅱ)膜电极的循环伏安图有明显的氧化还原蜂, 和彼此相似的电化学特性。聚8羟基喹啉膜(聚邻氨基酚, 聚邻苯二胺)可用以交换Ni(Ⅱ)与H~+离子和分离Ni(Ⅱ)、Co(Ⅱ)和Fe(Ⅱ)离子。

Abstract: Ni(Ⅱ) ion is complexed by poly-8-hydroxyquinoline, poly-0-aminophenol, poly-0-diaminobenzene and polyaniline as ligands. The voltammograms for the polymer-Ni (Ⅱ) film electrode show well defined reduction and oxidation peaks. They have similar electrochemical properties. Poly-8-hydroxyquinoline film, poly-0-aminophenol film and poly-0-diaminobenzene film can be used to exchange Ni (Ⅱ) with H~+ ion and to separate Ni(Ⅱ), Co (Ⅱ) and Fe(Ⅱ) ions.

Key words: Film electrode, Voltammograms, Electrochemical polymerization, 8-hydroxyquinoline, Aminophenol, Diaminobenzene, Aniline
