Description

Interaction of gadolinium(III) with nitrilotrimethylenephosphonic acid was studied by potentiometric method in a wide range of concentration ratios of components and ph at 298.15 K, ionic strength 0.1 (KNO3). Logarithms of protonation constants lg Kpr of GdL3-, GdHL2- particles equal to 7.88 ± 0.08 and 4.93 ± 0.05 respectively were obtained

Abstract (Russian)

Потенциометрическим методом исследовано взаимодействие гадолиния(III) с нитрилотриметиленфосфоновой кислотой в широком интервале концентрационных отношений компонентов и рН при 298.15 К, ионной силе 0.1 (KNO3). Получены логарифмы констант протонирования lg Kпр частиц GdL3-, GdHL2-, равные 7.88 ± 0.08 и 4.93 ± 0.05 соответственно
