FIELD: technological processes; chemistry. ^ SUBSTANCE: method for preparation of filter-sorption material includes application of silica-alumina mineral on substrate. Substrate used is basalt fibers, and silica-alumina mineral is bentonitic clay with montmorillonite content of at least 80%. Basalt fibers are processed by 5-7% water solution of alkali, bentonitic clay that has been previously exposed to soda activation is added, then mixed with addition of binding agent selected from aluminium salts, at ratio of bentonitic clay and binding agent equal to 1:3, heated at temperature of 50-100C for 2 hours, material is cooled, flushed by water and exposed to thermal activation at the temperature of 110-120C. ^ EFFECT: higher sorption capacity of filter-sorption material capable of regeneration, and expansion of material application sphere. ^ 3 tbl |
