FIELD: process engineering.
SUBSTANCE: invention relates to production of sorption and filtration materials for cleaning water from, mainly, manganese and iron. For production of sorbent, basalt fibers are used as a carrier. Said fibers are premixed in aqueous medium at mixing to sixes of 1 to 25 mm and chemically activated by inorganic acid. Said carrier is subjected to chemical treatment by bivalent manganese salt of concentration of 0.5 to 2%, medium pH is increased to 8 to 12 and hydrogen peroxide of concentration varying from 0.15 to 2% is added. Then, treated material is dried at 120-200°C and thermally treated at 250-350°C.
EFFECT: longer life, higher sorption capacity.
