Mechnikov National University popup.description2 The working is devoted to the study of chemical-analytical properties of 4-Sulfo-2(4'-sulfonaphthalene-1'-azo)-naphthol-1 (carmoazine - CAN) and of the products of its interaction with Hg(II), Mn(VII) and Ce(IV) ions in aqueous, aqueous-organic media and on a surface of woven materials (cotton, flax) by spectrophotometry, potentiometry and colorimetry methods. Based on the analytical forms found in the redox systems of the M- CAN, the Hg(II) and Mn(VII) determining methods have been developed in variants of the transmission spectroscopy, diffuse reflectance and visual colorimetry, and Ce (IV) - by the volume of the separated organic phase and spectrophotometrically, respectively, in waste waters, steels, wines, rocks, pharmaceutical samples bioactive addition "Spirulina and valerian root. The correctness of the developed techniques has been confirmed by analysis of standard samples of carbon steels of U1k and UNL8v types, rock "Gabbro Esseksitovoe, Lake Baikal bottom silt.
