Abstract
The extraction equilibria of Ni(II) from nitrate medium by mixtures of the active component in the commercial LIX 63, 5,8-diethyl-7-hydroxyd odecan-6-oxime (HDEHO), and bis(2-ethylhexyl)phosphoric (HDEHP) or di- n-octylphosphinic (H[DOP]) acids dissolved in toluene have been studie d. Large synergistic effects have been obtained in both cases and mixe d metallic species have been proposed to explain the experimental extr action of Ni(II) by these mixtures. Equilibrium constant values of the extracted species are also given.
