Characteristics of Palladium(II) Complex with 1-Nitroso-2-Naphthol-3,6-Disulfonic
Acid
Abstract
Optimal conditions of
complexation palladium(II) with 1-nitroso-2-naphthol-3,6-disulfonic acid were
found by spectrophotometric method (an optimum interval pH
1,2–3,8, the five-multiple surplus reagent). Analytical characteristic of a
complex in an interval concentration of palladium(II) (0,94 – 8,46)´10–5 M are determined, e = (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] и Z [(5,6±0,2)´105] (n = 5, P = 0,95).
