Optical and Chromaticity Characteristics of Rare-Earth Element Complexes of Sulfochlorophenol and Sulfochlorophenol S
Tóm tắt
Optimal conditions of the complexation of Sulfochlorophenol and Sulfochlorophenol S with lanthanum, terbium, and erbium were found, and molar absorptivities of the complexes were calculated. Chromaticity characteristics of the complexes and molar coefficients of chromaticity functions were determined. It was demonstrated that the use of the most sensitive chromaticity functions provides an increase in the sensitivity of the determination of rare-earth elements of 1–2 orders of magnitude in comparison with conventional spectrophotometry. Dissociation constants of the reagents were determined using optical and chromaticity methods.
