INFLUENCE OF TRIBUTYLPHOSPHATE AND DI-(2-ETHYLHEXYL)PHOSPHORIC ACID MIXTURE ON THE EXTRACT OF NEODYMIUM FROM ACID MEDIUMS
He paper is devoted to researching the effect of di-(2-ethylhexyl) phosphoric acid and tributylphosphate mixture on the extraction of neodymium from acid mediums. The extraction of neodymium by individual extractants - tributylphosphate and di-(2-ethylhexyl) phosphoric acid from muriatic, nitric and sulfuric mediums was scrutinized, and the rates of the neodymium extraction were calculated. Experimental data on the extraction of neodymium from acid mediums by isomolecular mixture of extractants and calculated synergistic rates of extraction are also presented in the paper. Finally some concluding considerations on the effectiveness of the extractant mixture applying to recover the neodymium from acidic environments are presented based on experimental data.
