Abstract :Using lead 4-benzylpiperidinedithiocarbamate complex insert ignore into journalissuearticles values(Pbinsert ignore into journalissuearticles values(4-BPDC);2);, a solid-phase extraction method was developed for pre-concentration and spectrophotometric determination of copper in water samples. In this method, copper in large volume liquid phase quantitatively replaces lead on colorless Pbinsert ignore into journalissuearticles values(4-BPDC);2 complex and naphthalene solid phase mixture forming Cu-4-benzylpiperidinedithiocarbamate complex insert ignore into journalissuearticles values(Cuinsert ignore into journalissuearticles values(4-BPDC);2);. The solid phase containing colored Cuinsert ignore into journalissuearticles values(4-BPDC);2 is dissolved in chloroform and its absorbance is measured at 437 nm against the reagent blank. The range of linearity is 0.4 -10 m gml-1 of copper in chloroform, the molar absorptivity of the complex determined from the linear portion of Beer`s law plot is 8.197x103 lmol-1cm-1 and the sensitivity is 0.0013 m gcm-2 for an absorbance of 0.001.
