近年来,修饰电极的制作并用于电化学分析的报道越来越多,对银敏感的修饰电极也有一些报道。柄山等人利用玻碳电极经湿法氧化或还原后制作IDA,EDTA和GEDTA修饰电极,测定低至1×10~(-6)mol·L~(-1)Ag~+。力虎林等利用光谱纯石墨电极,经湿法氧化,使表面赋于极性后,或者浸渍聚丙烯腈,再经羟胺化后制成聚丙烯酰胺肟修饰电极,富集时间30min,低至1×10~(-8)mol·L~(-1)Ag~+仍可测定;或
In recent years, more and more reports on the fabrication of modified electrodes and their application in electrochemical analysis have also been reported. There are also reports on silver-modified electrodes. Tianshan et al. Fabricated IDA, EDTA and GEDTA modified electrodes by using glassy carbon electrode after wet oxidation or reduction, and measured as low as 1 × 10 -6 mol·L -1 Ag ~ +. Li Hulin and other use of pure graphite electrode, the wet oxidation, the surface is given after the polarity, or impregnated polyacrylonitrile, and then hydroxylamine polyacrylamide modified oxime electrode, enrichment time 30min, as low as 1 × 10 ~ (-8) mol·L ~ (-1) Ag ~ + can still be measured; or
