The aim of the present paper is investigation of removal of Fe 3 + and Pb 2 + ions from aqueous media by material on the basis of steel melting slag. It has been established that the process of water purification from Fe 3 + and Pb 2 + ions by this material proceeds by a mixed mechanism both due to the formation of slightly soluble silicates and also due to the formation of hydroxides. When the filtration rate varies from 2 to 10 column volumes per hour, the percentage of sorption remains within 91,5–99,8%. The most optimal filtration rate is 6 column volumes per hour. Material on the basis of steel melting slag absorbs of Fe (III) up to 5 mg-eq/g and Pb (II) 0.64–1.27 mg-eq/g.
