Liquid-Liquid Extraction of Cobalt(II), Nickel(II) and Manganese(II) from Acidic Chloride Media

Abstract

The extractionExtractionproperties of two synthesized cationic exchangers, i.e. bis(1,3-dibutoxypropan-2-yl) phosphoric acid (BiDiBoPP) and bis(1,3-diisobutoxypropan-2-yl) phosphoric acid (IPA), have been studied for the liquid-liquid extractionExtractionof Co(II), Ni(II)Ni(ii)and Mn(II) contained in 1 M HCl. A comparison of the extractionExtractionproperties of these extractants diluted in kerosene withCyanex®Cyanex®272 shows BiDiBoPP and IPA extract advantageously at lower pH than Cyanex®272 and a better Co(II)-Mn(II) separationSeparationis achieved using BiDiBoPP or IPA than with Cyanex®272.
