摘要：
Extraction of microamounts of U(VI), Th(IV), Sc(III), and Ln(III) from HNO3 solutions with solutions of bis(diphenylphosphinylethyl) phosphinic acid in dichloroethane was studied. The stoichiometry of the extractable complexes was determined, and the effect of the inorganic anion and organic diluent on the extraction of rare-earth elements was examined. An increase in the number of phosphoryl groups in the extractant molecule and replacement of ethylene bridges between the phosphorus atoms by methylene bridges enhance the extraction of metal ions from nitric acid solutions. ©2005 Pleiades Publishing, Inc.
