Conclusions

  1. 1.

    The extraction of 12 metals by diheptylethylene disulfide (DHEDS) and that of Pt(IV), Au(III), and Pd(II) by diheptylmethylene disulfide (DHMDS) from hydrochloric acid solutions were studied. Of the investigated elements, only gold and platinum are extracted by DHEDS in the entire range of hydrochloric acid concentrations; gallium (III) and mercury (II) are extracted into the organic phase from strongly and weakly acid solutions of HCl, respectively.

  2. 2.

    The mechanism of the extraction of palladium by DHEDS from a solution of 3 M HCl was investigated.

  3. 3.

    The formation of a cyclic monosolvate complex with predominant coordination of the extraction reagent to the metal through the sulfur atoms was established.
