摘　　要：乙酰丙酮缩邻氨基苯酚对铜的萃取性能及萃取光度法＊唐丽素刘春元龙云飞周建军（湘潭师范学院化学系湖南湘潭４１１１００）关键词乙酰丙酮缩邻氨基苯酚铜（Ⅱ）萃取分光光度法中图分类号Ｏ６５７．３２对铜的萃取分离已做了大量的研究工作，并在湿法冶金工业获得了应用［...The extractive behavior and extractive spectrophotometry of a novel schiff base ligand H 2acac o ap in CHCl 3 solution to Copper(Ⅱ) were studied.The experimental findings showed that the extractant complexed divalent copper had a ratio 1∶1.Under the nertral or weaker acidic conditions trace copper in aqueous phase was selectively and quantitatively extracted to organic phase (CHCl 3).The λ and ε of the chloroform extract were measured at 400nm and 1.28×10 4,respectively.And Beer′s law was applicable in the rang of 0～3μg/ml for copper.The proposed method can be used in separating and directly determinating trace copper without anti extraction.
