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

Optimal conditions of complexation palladium(II) with 1-nitroso-naphthol-3,6-disulfonic acid were found by the spectrophotometric method (an optimum interval pH 1.2–3.8, a five-multiple surplus reagent). The analytical characteristics of a complex in an interval concentration of palladium(II) (0.94–8.59) × 10⁻⁵ M are determined, ɛ = (9.80 ± 0.02) × 10³ (n = 9, P = 0.95). The function and molar coefficient of chromaticity are determined. The most sensitive functions are G [(7.6 ± 0.1) × 10⁵] and Z [(5.6 ± 0.2) × 10⁵] (n = 5, P = 0.95).
