Spectrophotometric determination of copper in pharmaceutical and biological samples with 3-[2-[2-(2-hydroxyimino-1-methyl-propylideneamino)-(ethylamino]-ethyl-imino]-butan-2-one oxime)

3-[2-[2-(2-hydroxyimino-1-methyl-propylideneamino)-ethylamino]-ethyl-imino]-butan-2-one oxime, (H(2)mdo) reacts with copper(II) to form a highly stable 1:1 complex in alkaline medium at room temperature. The complex gives a maximum absorption at 570 nm with a molar absorptivity coefficient of 0.16 x...
