A possibility of the analytical application of a low-melting extractant, antipyrinium acetylsalicylate, to the extraction of a number of ions from acid aqueous solutions is studied. The distribution of Al, As, Cd, Co, Cr, Cu, Fe, Mg, Mn, Mo, Ni, Pb, Sb, Sn, Ti, V, and Zn ions between the aqueous solution and an organic extractant is studied by atomic emission spectrometry. The efficiency of ion extraction from acid solutions with a low-melting flux of antipyrinium acetylsalicylate is calculated. It is shown that single extraction with an extractant flux ensures the efficient extraction of Fe, Mo, Sn, and Ti from the water phase of the analyzed solution to the flux. The introduction of chloride ions into the analyzed acid aqueous solution significantly increases the efficiency of the group preconcentration of ions by the ion-exchange mechanism.
