Abstract

Extraction of lanthanide(III) nitrates [La-Sm(III)] with 1.83 mol dm−3 tri-n-butyl phosphate (TBP) in hexane and tetradecane was studied at 298.15 K. The extraction with TBP in hexane proceeds in two-phase systems, and with TBP in tetradecane, in two- and three-phase systems. Extraction in multiphase systems was mathematically treated.
