Optical and chromaticity characteristic of the analytical
forms solutions sulphate, cloride, formate and acetate of chromium (III)
Abstract
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 410–420 and 560–580 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 1–1,5 about in comparison with molar coefficients
absorption. In all cases
the yellowness is maximal.
