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.
