| Abstract: | A red violete complex of copper() with 1,5di(2hydroxy5sulfophenyl)3cyanoformazan disodium salt(DSPCF) was formed in the medium of HAcNaAc.The wave length of maximum absorbance of complex is 580nm.Apparent molar absorptivity is 4.8104Lmol-1cm-1.The color reaction is accomplish instantly.The colored complex is stable within 24h.Beers law is obeyed in the range 0-0.8mg/L for copper().Satisfactory result was obtained for determination of microamounts copper in water. |
