摘要
报道了溴化十六烷基三甲胺ＣＴＭＡＢ与乳剂ＯＰ共存时，在硫酸、盐酸介质中，用苯芴酮分光光度法测定铜合金中锡的研究．该混配颜色化合物的λｍａｘ ５０５ｎｍ，εｍａｘ ５．２４×１０６ Ｌ·ｍｏｌ－１ｃｍ－１，锡的检量范围０～５０μｇｍＬ－１，服从朗伯—比尔定律，具有较高的灵敏度、选择性，重现性、稳定性也较好，适用于工厂中铜合金锡的检测．
The multi-ligand chromogenic reaction system of Sn(II)phenylflurone CTMAB OP and the method of spectrophotometric determination are studied.The maximum absorption at 505 nm and the molar absorptivity of complex are 5.24×10 6 L·mol -1 ·cm -1 .The examination range of Sn is found out to be O～50～μg·ml -1 .The application of the spectrophotometric method to imdustrial production is also discussed. ①
