摘要
研究在ＰＶＡ－ＡＧ（聚乙烯醇－阿拉伯胶）存在和不同酸度下，Ｍｎ＋－Ｂｒ－－Ｒ６Ｇ（金属离子－溴化物－罗丹明６Ｇ）的显色体系．文中列出几个摩尔吸收系数ε＞４．３×１０５的高灵敏显色体系的分析特性，并用于测定水样中铅．
In the presence of polyvinyl alcohol and arabic gum, the color developing systems of metal ion-bromide-rhodamine 6G is studied under variable acidity.Several high sensitive color developing systems of metal ion-bromide-rhodamine 6G are obtained through screening;and their characteristics of analysis are enumerated. These systems have been applied to the determination of trace lead in water sample.
