Abstract
Distribution of lanthanide(III) and yttrium(III) [Ln(III)] nitrates an d also water between aqueous solutions and tri-n-butyl phosphate at T = 298.15 K was studied. Equations were proposed to describe extraction equilibria, taking into account variation of the water content and no nideality of the organic phase.
