Optical and chromaticity characteristics of copper(II) complex with 1-nitroso-2-naphthol-3,6-disulfonic acid


Optimal conditions of complexation copper(II) with 1-nitroso-2-naphthol-3,6-disulfonic acid were found by spectrophotometric method. An optimum interval pH of formation of a complex 6,5 7,9. The ten-multiple surplus reagent suffices for quantitative formation of a complex. Chemical analytical and characteristic of a complex in an interval concentration of copper (1,26 6,39)´105 M are determined. Molar coefficient of absorption of a complex is equal (1,210,01)´104 (n = 5, P = 0,95). The function and molar coefficient of chromaticity are determined. The most sensitive functions are Z [(2,58 0,04)´105] and G [(3,88 0,06)´105] (n = 5, P = 0,95).
