FIELD: filtration processes. SUBSTANCE: filtering material for selective separation of organic and inorganic phases is prepared from pressed activated carbon through following steps. Activated carbon is mixed with polyvinyl alcohol at (3-9):1 ratio. Obtained blend is mixed with distilled water or with its mixture with ethyl alcohol whereupon pellets or similar objects are press-molded. The pellets are then heated for 3-6 h at 40-80 C and for further 10-14 h at 80-120 C. EFFECT: improved quality of material.
