摘要
研究了ＴＳＡＢ、ＣＴＭＡＢ与Ｓｂ（Ⅲ）的反应条件。在ｐＨ３．５～５．２范围内，Ｓｂ（Ⅲ）与ＴＳＡＢ形成稳定的１：２络合物，其最大吸收波长为４７０ｎｍ，摩尔吸光系数为３．１２×１０４。０～９０μｇＳｂ／２５ｍｌ符合比尔定律、用于锌合金中锑的测定，结果满意。
The colour reaction of antimony with TSAB and CTMAB has been investigated.The absorption peak of the complex is at 470nm.The molar absorptivity is 3.12×104.The composition of the complex has been estimated to be Sb:TSAB = 1 : 2 in the presence of CTMAB. Beer's law is obeyed in the range of 0 -90μg/25mlfor Sb.The method has been applied satisfactorily to the determination of micro amounts of Sb in zinc alloys.
