摘　　要：本文研究了铅与邻氯苯基荧光酮(o-CPF)及溴化十六烷基三甲铵(CTMAB)显色反应的最佳条件,并将此法用于实际样品的测定.获得了满意的分析结果.In this paper, spectrophotometric determination of microamo'unts of Al with o-chlorophe-nylfluoi-a'ne and cetyltrimethylammonium bromide is described. The molar absorptivity of the complex is 1.35×105 at 56'6nm. Beer's law is obeyed in the range of o to 8ug/50ml for Al. It has been directly used to determine Al in steel and limestone etc with satisfactory results.
