Abstract

Extraction of lanthanides and actinides were found to be synergically enhanced by a mixture of bis/2-ethyl hexyl/phosphoric acid /HA/ and dinonylnaphthalene sulfonic acid /HD/ in aromatic diluents covering a wide range of dielectric constant. The main extracted species is found to be in the form MA2Hm−1Dm. Experimental results indicate that the extraction mechanism is governed by the extraction of HD in the organic phase.
