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。
Ni (Ⅱ) ions with poly 8-hydroxyquinoline, poly-o-aminophenol, poly-o-phenylenediamine and polyaniline complexed. Cyclic voltammograms of the polymer-Ni (II) membrane electrode have obvious redox bees and similar electrochemical properties to each other. Poly (8 - hydroxyquinoline) membrane can be used to exchange Ni (Ⅱ) and H ~ + ions and to separate Ni
