Iridium(IV) extraction with petroleum sulfoxides from hydrochloric acid solutions

Abstract

Iridium(IV) extraction with petroleum sulfoxides (PSO) from hydrochloric acid solutions is studied. Optimum conditions of extraction are chosen. It is shown that in the investigated extraction systems for a phase contact time of 30 min, iridium(IV) is extracted by the ion-associative mechanism. Electronic, 1H NMR, and IR-spectroscopy, and elemental analysis are used to establish the structure of the extracted compound.
