摘要
The reagent, 2-acetylthiophene thiosemicarbazone (ATT) has been synthesized and characterized based on spectral data. The reagent gives intense yellowish green Coloured complex (lambda(max) = 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 x 10(4) L. mol(-1) cm(-1) and 0.0034 mu g of Cu(II) cm(-2) respectively. The method has been used for the determination of copper(II) in alloys, edible oils and seeds.
