Abstract: The reagent, 2-acetylthiophene thiosemicarbazone (ATT) has been synthesized and characterized based on spectral data, The reagent gives intense yellowish green coloured complex (λmax=370 nm) with copper(II) in sodium acetate-acetic acid buffer (pH 5-7) medium. The colour reaction has been investigated in detail. The molar absorptivity and Sandell's sensitivity of the copper(II) complex of ATT are 1.83 × 104 L. mol-1 cm-1 and 0.0034 μg of Cu(II) cm-2 respectively. The method has been used for the determination of copper(II) in alloys, edible oils and seeds.
