FIELD: processes for extracting matters with use of sorbents, possibly in non-ferrous and ferrous metallurgy, for cleaning industrial and domestic sewage. ^ SUBSTANCE: sorption is realized on anionite containing groups . Before sorption anionite is subjected to preliminary acidic, alkali or aqueous treatment. Sorption is realized for period less than 2 h, namely after preliminary acidic treatment of anionite at pH =4 - 5 or 7 - 8; after alkali treatment of anionite at pH 3 - 6 and after aqueous treatment at pH = 2.4 - 8.5. ^ EFFECT: determination of optimal conditions for rapid and effective extraction of manganese VII ions out of aqueous solution. ^ 5 dwg, 4 ex |
