FIELD: water treatment. SUBSTANCE: removal of iron-containing compounds from water is carried out by adsorption of iron ions. Adsorbent: carbon-containing adsorbent mineral base prepared of the natural clay or aluminium oxide with carbon coating. Depleted adsorbent is regenerated by its treatment with oxalic acid, washed with water. Then the adsorbent surface is adjusted up to the neutral value with weak alkaline solution. EFFECT: improved method of water treatment. 1 dwg, 1 tbl
