Zusammenfassung:	PCT No. PCT/EP86/00437 Sec. 371 Date Mar. 26, 1987 Sec. 102(e) Date Mar. 26, 1987 PCT Filed Jul. 23, 1986 PCT Pub. No. WO87/00867 PCT Pub. Date Feb. 12, 1987.A process for separating arsenic from acid aqueous solutions containing arsenic and other metal ions. The process involves bringing the acid aqueous solution into contact with a water-immiscible organic diluent consisting of hydrocarbons, alcohols or their mixtures, in which there is dissolved as solvent at least one polyol. The solvent thereby extracts the arsenic, which is then re-extracted with a counter-solvent.
