This work presents the experimental study results of Fe(III) and Zn(II) extraction by ionic liquids based on trioctylmethylammonium chloride and rhodanide in an aqueous two-phase system based on polypropylene glycol 425 and sodium chloride. Based on the results obtained, it was concluded that these extractants are effective for the extraction of metals from aqueous solutions, and aqueous two-phase systems represent a “green” alternative to traditional extraction systems.
