conductimetric, IR, NMR and TGA studies have been carried out on the complexes of trivalent yttrium, lanthanum, praseodymium, neodymium, samarium, gadolinium and erbium with some azo derivatives of 3-hydroxy-2-naphthoic acid. The ionization constants of the reagents and the formation constants of their metal complexes have been determined potentiometrically by Sarin's method. Complexation has also been studied
摘要 对三价钇、镧、镨、钕、钐、钆和铒与3-羟基-2-萘甲酸的一些偶氮衍生物的配合物进行了电位、电导、红外、核磁共振和热重分析研究。试剂的电离常数和它们的金属配合物的形成常数已通过沙林法电位测定。还通过电导滴定法研究了络合,分离、分析了形成的固体络合物,并通过 IR、NMR 和 TGA 研究阐明了它们的结构。
