The characteristics and mechanism of the adsorption of gold in hydrochloric acid medium by impregnated resin N₅₀₃ N,N-di(sec-octyl) acetamide have been studied. The ratio of gold to N₅₀₃ in the adsorbate is 1:2. IR and chemical analysis show that the gold is adsorbed in form of AuCl₄^-. The adsorption is an ion association reaction:2N₅₀₃+H⁺+AuCl₄^-=(N₅₀₃)₂·H⁺·AuCl₄^- Gold in ores has been seperated and determined by N₅₀₃ satisfactorily.
