Carbon disulfide and pyrrolidine containing p-xylene was proved to be useful and convenient for metal extraction. The procedure involved forming pyrrolidine dithiocarbamic acid during the course of extraction and solidifying the organic phase by cooling in a centrifuge. Metal ions such as Cd2+, Ni2+, Co2+, and Zn2+ could be extracted into the organic phase without using any chelate extractant.
