ABSTRACT:
A simple extractive spectrophotometric method has been developed for the determination of Cu(II) by using Isatin - 3 - Thiosemicarbazone(HITSC) as an analytical reagent .HITSC has been synthesized and characterized by elemental and spectral analysis. HITSC extracts Cu(II)quantitatively (99.67%) into Nitrobenzene from an aqueous solution of pH range 5.5– 6.5. Nitrobenzene extract shows an intense peak at460 nm (? max).Beer’s law is obeyed over the Cu (II) concentration range of 1.0 to 5.0µg/ml. The Sandell’s sensitivity and molar absorptivity for Cu-HITSC system is 9.523ngcm-2and 6673.02L mole-1cm-1 respectively. The composition of extracted species is found to be 1:2 (Cu: HITSC) by Job’s Continuous Variation and Mole Ratio Method. Interference by various ions has been studied. The proposed method has been successfully applied for determination of Cu(II) in pharmaceutical sample and Al-alloy.
