Studies on extraction of zirconium by quaternary ammonium halides from hydrochloric acid media and its separation from hafnium.
The distribution of Zr(IV) between hydrochloric acid media and Hyamine 1622 in the organic phase is described. The dependence of extraction on acidity, extractant concentration and type of diluent, was investigated. The possible extraction mechanism is discussed in the light of the results obtained. A method for the separation and determination of Zr(IV) in a mixture of Zr and Hf is outlined.
