本文研究了聚邻氨基酚(POAP)膜的络合与再修饰。POAP膜可分离与交换Fe~(2+)、Co~(2+)、Ni~(2+)等第八族元素。POAP-Fe(CN)_6~(3-)膜有稳定的氧化还原电流峰,电位漂移小,重现性好,适合于制成新型参比电极。再修饰的POAP-四氯苯醌具有良好的pH特性。
This article studies the poly-o-aminophenol (POAP) membrane complexation and re-modification. POAP membranes can separate and exchange Group VIII elements such as Fe ~ (2 +), Co ~ (2 +) and Ni ~ (2+). The POAP-Fe (CN) 6 ~ (3-) film has a stable redox current peak with small potential drift and good reproducibility, which is suitable for making a novel reference electrode. The modified POAP-chloranil has good pH properties.
