摘要
本文介绍了用兴多偶氮氯膦Ⅰ分光光度法测量铜合金中铝的方法。在ＰＨ值为５．５的乙酸－乙酸钠介质中，铝与兴多偶氮氯膦Ⅰ形成的配合物最大吸收峰在６１５ｎｍ处，摩尔吸光系数为２．０×１０４，铝量在０～１０μｇ／２５ｍｌ范围内符合比尔定律。该法简便快速，直接测定铜合金中微量铝，取得了满意的结果。
This paper introduces a method for determining trace Al in copper alloy used of chlorophosphonazo Ⅰ spectrobphotometry In the medium of acetic acid sodium acetate with 5 5 PH value the greatest peak value of mixture formed by chlorophosphonazo Ⅰ whth Al is at 615nm,and mol absorption light coefficient is 2 0×10 4,and aluminium quantity is to accord with Beers law within the limite of 0～10μg/25ml This method can directly determine trace Al in copper alloy and can get satisfactory result
