Optical and chromaticity characteristic of the analytical forms solutions sulphate, cloride, formate and acetate of chromium (III)


The conditions of formation and spectra absorption of solutions chromium (III), received by reduction sulfate sodium, ascorbic acid or hydrogen peroxide of solutions chromium(VI) are investigated. The solutions have maxima absorption at 410420 and 560580 nm and molar coefficients absorption from 17 up to 80. Are investigated chromaticyc function of the specified forms chromium(VI) and is shown, that they are higher on 11,5 about in comparison with molar coefficients absorption. In all cases the yellowness is maximal.
