The solvent extraction of metal ions by quaternary ammonium halides dissolved in 1,2-dichloroethane is described. The extraction is dependent upon the ion association of the quaternary ammonium ion with labile chloro anionic complexes of Fe (III), Co(II), Zn(H), and Tl(III) or with the oxyanions of Hf(PJ), Ta(V), and Mo(VI) in concentrated hydrochloric acid or lithium chloride. The effects of metal ion concentration, contacting time, and type of quaternary ammonium halide are investigated with the cobalt ion. Extractions of >50% for cobalt are possible only if the distribution ratio of the quaternary ammonium halide itself is very large. The value of the distribution ratio of the cobalt ion is dependent upon the quaternary ammonium ions' size, shape, and type of organic groups. An analogy between solvent extraction with quaternary ammonium halides and anion exchange of metal ions in concentrated hydrochloric acid is demonstrated. (auth)
