摘要
用分光光度法研究了氨三乙酸合钕(III)与4-[(8-羟基-5-喹啉)偶氮]苯磺酸、邻-[(5-羟基-3-甲基-1-对苯磺酸基-4-吡唑基)偶氮]苯甲酸及乙二胺四乙酸合钕(III)与2-羟基-5-[(4-苯磺酸基)偶氮]苯甲酸的混配络合物的加合平衡,测得了它们的平衡常数.
The addition equilibrium of mixed ligand complexes Nd (Ⅲ)-NTA-HQAB, Nd (Ⅲ)-NTA-HPAB, Nd(Ⅲ)-EDTA-Solo 2G (HQAB: 8-hydroxy-5-(p-sulfo-phenylazo) quinoline, HPAB: acid mordant yellow 8, Solo 2G: 5-(4'-sulfophenylazo)salicylic acid)have been studied spectrophotometrically. Their equilibrium constants have been obtained.
