Extraction of rare-earth metal(III) (REM) [praseodymium-lutetium, yttrium(III)] nitrates by solutions of trialkylmethylammonium nitrate in kerosene (0.4-1.0 M) was studied. It was established that di- and trisolvates are formed in the organic phase. Extraction constants were determined. Physicochemical and mathematical models were developed to describe the extraction of REM(III) nitrates from binary and multicomponent aqueous solutions. The range of REM nitrate concentrations in the aqueous providing optimal conditions for extraction separation of REM by trialkylmethylammonium nitrate solutions in kerosene was established.
