摘要：

Lanthanum nitrate distribution in three-component aqueous-organic systems with D2EHPA from acetate or acetic acid-acetate solutions has been studied, it has been shown that variation in sodium acetate concentration or composition of CH3COONa-CH3COOH mixture can affect metal distribution ratios. It has been found that extraction in three-component mixture of 1: 1: 1 composition (aqueous solution Ln(NO3)(3) + CH3COONa + CH3COOH-D2EHPA in hexane-isopropyl alcohol) can provide lanthanide separation, which is dependent on the ratio of sodium acetate and acetic acid in aqueous phase and on D2EHPA concentration in organic phase. Lanthanide-lanthanum separation factors have been calculated for the extraction of lanthanide nitrates from acetic acid-acetate solutions.
