SYNTHESIS OF AZODERIVATIVES OF CHROMOTROPIC ACID AND INVESTIGATION OF ITS COMPLEXFORMATION WITH COBALT(II) IN THE PRESENCE OF THIRD COMPOUNDES
Complex formation of cobalt(II) with 2-[2-dihydroxy-3,5-disulphenylазо]naphthalene-1,8-dihydroxy-3,6-disulphosodium has been investigated in the presence and absence of surfactants–cetylpyridinium chloride, cetylpyridinium bromide, cetylpyridiniumtrimethylammonium bromide. Molar absorbtivities and stability constants of complexes have been determined. The determined concentration interval obeys to Beer’s law. The developed technique was applied to determine cobalt(II) in the Akstafa and Jogaz rivers of the Kazakh region of the Azerbaijan Republic
Keywords : cobalt(II), surfactants, cetylpyridinium chloride, cetylpyridinium bromide, cetyltrimethylammonium bromide, complexes of cobalt(II)
