The results of experimental investigation of the interphase distribution of iron(III) in an environmentally friendly aqueous two-phase system based on polypropylene glycol with a molecular weight of 425 and sodium chloride have been presented. The mechanism of extraction has been determined, and the quantitative characteristics of the extraction of iron(III) using the system under study have been found.
