摘要
提出了铝—茜素红S-甲基紫-聚乙烯醇三元配合物体系光度法测定铝的新方法，该方法灵敏度高（t=2．09×10^4L·mol．cm^-1），精密度可靠，用于测定化学试剂中的痕量铝，结果满意。
the spectrophotometric determination of trace aluminium with ternary complex system of Al（Ⅲ）-alizarin red-methyl violet-polyethyiegiycol has been introduced. The method has high sensitivity and reliable accuracy. It has been used to determination trace aluminium in reagent and has satisfactory results.
