Abstract

Extraction of nitrates of lanthanides(III) [La(III)-Lu(III) and also yttrium(III)] from their aqueous multicomponent systems with a toluene solution of trialkylbenzylammonium naphthenate was studied at 298 K and pH 3. Physicochemical and mathematical models describing the distribution and mutual influence of lanthanides(III) [Ln(III)] in their joint extraction from multicomponent aqueous solutions as influenced by the total Ln(III) concentration in the aqueous phase and composition of their mixture was developed.
