FIELD: chemistry.SUBSTANCE: invention relates to porous carbon materials. Disclosed is a material obtained by reducing silicon content in plant material, such as sugar cane, seaweed stems, rice husks and straw. The method of producing porous carbon material from silicon-containing plant material involves carbonising plant material during high-temperature treatment, treating with acid or alkali, followed by activation. The disclosed carbon material has nitrogen BET specific surface area of at least 10 m/g, mesopore volume of at least 2.2 cm/g, measured by mercury press-in method, mesopore volume of at least 0.1 cm/g, measured by BJH method and MP method. The obtained carbon material can be used, for example, as a medical adsorbent, a creatinine adsorbent, a cap for blood purification columns, a water treatment adsorbent, an adsorbent sheet, a medicine carrier and a carbon-polymer complex.EFFECT: invention enables to obtain material with high functionality.10 cl, 10 dwg, 12 tbl, 8 ex |
