|Abstract:||Diacetylmonoxime benzoylhydrazone (DMBH), a novel class of oxime-hydrazone has been synthesized and characterized based on elemental analysis, IR, NMR and mass spectra data. The reagent gives intense colour reactions with nickel(II) and copper(II) in basic medium. Hence direct spectrophotometric methods for the determination of nickel (II) and copper(II) have been developed in aqueous medium. The molar absorptivity and Sandell's sensitivity of the methods for Ni(II) and Cu(II) are 2.13×104, l.36×104 L. mol-1 cm-1 and 0.0028 and 0.0047 μg/cm2 respectively. Beer's law is obeyed in the ranges 0.12-2.58 μg/ml and 0.25-2.0 μg/ml for nickel(II) and copper(II) respectively. First derivative spectrophotometric technique has been used for the simultaneous determination of nickel(II) and copper(II) using DMBH in alloys.|
