Abstract

Extraction of lanthanides(III) [La(III)-Lu(III)] and yttrium(III) with toluene solution of trialkylbenzylammonium naphthenate mixture was studied. The equations of extraction isotherms taking into account formation of the extractable complexes (R4N)2[Ln(NO3)3A2] (A is naphthenate anion) were obtained. The extraction constants of lanthanides [La(III)-Lu(III] and yttrium(III) were calculated.
