摘要
本文研究了Al3 + 与新显色剂二溴对甲基偶氮羧显色反应的影响因素 ,建立了测定铝的新的光度分析法 ,其表观摩尔吸光系数为 2 .2× 10 4 ,Al3 + 量在 0～ 2 5 μg/ 2 5ml内符合比耳定律 。
The factors of reaction of new chromogenic reagent dibromomethyl carboxyazo with Al 3+ were stu died. The method of the Spectrophotometric Determination of trace aluminium was found.The mole absorptivity coefficient is 2.2×10 4,and the Al 3+ content is in the 0～25μg/25mL agreed with the Beer’s law.This method can be also used in determining the trace iron in silicate samples.
