FIELD: production of filtering materials possessing high adsorbing and filtering abilities.
SUBSTANCE: proposed method consists in production of filtering material on base of non-woven polymer material for modification of its fibers by charged particles of aluminum hydroxide by means of impregnation at elevated temperature in solution containing aluminum salts and additionally carboxylic acid and/or hydroxy-carboxylic acid and/or their salts. In the course of impregnation, particles of aluminum oxide hydrate of non-spherical form are formed and are fixed on fibers of non-woven polymer material. Proposed method makes it possible to produce filtering material possessing high filtering ability due to increased number of nano-particles fixed on fibers of non-woven polymer material.
EFFECT: enhanced efficiency.
