Description

The complexation of Sm(III)EDTA- with acetate (Ac-), glycinate (Gly-), iminodiacetate (Ida2-), and nitrilotriacetate (Nta3-) ions in aqueous solution was studied at 298.15 K and I = 0.5 (KNO3). The formation of mixed-ligand complex ions SmEdtaAc2-, SmEdtaAc23-, SmEdtaGly2-, SmEdta(OH)Gly3-, SmEdtaIda3-, SmEdtaHIda2-, and SmEdtaNta4- was revealed. Log stability constants for these complexes were calculated

Abstract (Russian)

Потенциометрическим методом исследовано комплексообразование SmEdta- с ацетат- (Ac-), глицинат- (Gly-), иминодиацетат- (Ida2-) и нитрилотриацетат- (Nta3-) ионами в водном растворе при 298.15 К и I = 0.5 (КNО3). Установлено образование смешаннолигандных комплексных ионов состава SmEdtaAc2-, SmEdtaAc23-, SmEdtaGly2-, SmEdta(OH)Gly3-, SmEdtaIda3-, SmEdtaHIda2-, SmEdtaNta4-. Рассчитаны логарифмы констант устойчивости данных комплексов
