FIELD: medicine, pharmaceutics.SUBSTANCE: group of inventions refers to a method for preparing a carbon sorbent with the antibacterial properties, and to the carbon sorbent with the antibacterial properties prepared by this method. The declared method involves impregnation of the carbon hemosorbent granules in an initiator solution in N-vinylpyrrolidone at pH 7.0-7.5 and a residual pressure of 15-20 mm Hg. The hemosorbent : initiator solution in N-vinylpyrrolidone ratio is 1:1.4-2.0. Then the temperature is raised to 65-75°C, kept at that temperature for 0.5-8 hours in an inert medium and washed in water from the residual monomer at room temperature.EFFECT: carbon sorbent with the antibacterial properties prepared by the specified method represents the round granules, contains polyvinylpyrrolidone in an amount of 4,5-5,5% and is characterised by a specific surface adsorption of less than 50 m/g and total pore volume of less than 0,30 cm/g.2 cl, 2 tbl, 1 dwg, 7 ex |
