摘　　要：研究了在溴化十六烷基三甲基铵存在下，锆（Ⅳ）与３，５－二溴水杨基萤光酮的显色反应，在０．３ｍｏｌ·Ｌ－１ＨＣｌ介质中，Ｚｒ（Ⅳ）同上述试剂形成橙红色胶束三元络合物，其最大吸收波长在５２１．６ｎｍ摩尔吸光系数为１．５２×１０５Ｌ·ｍｏｌ－１·ｃｍ－１。锆量在０～２０μｇ／２５ｍＬ符合比尔定律。A study on color reaction of microamounts zirconium with 3,5-dibromosalicylfluorone and cetylerimethylammonium bromide has been developed. In acidic solution (0.3 mol\5L -1 HCl) zirconium forms a red-orange colored micellar trnary complex with the above reagents, exhibiting maximum absorption at 521.6nm. The molar absorption coefficient of this complex is 1.52×10 5L\5mol -1 \5cm -1 . Beer′s law is obeyed for zirconium in the range of 0～20 μg/25mL.
