Nalichie antibiotikov v svyazi s povysheniem ih promyshlennogo proizvodstva vse chasche registriruetsya v stochnyh vodah, pochvah, gruntovoy i pit'evoy vode. V svyazi s etim ochistka okruzhayuschey sredy ot farmacevticheskih preparatov – odna iz aktual'nyh ekologicheskih zadach. Sintez adsorbentov iz razlichnyh vidov syr'ya s ispol'zovaniem metodov mehanohimicheskoy aktivacii pozvolyaet suschestvenno povysit' sorbcionnuyu sposobnost' dannogo materiala za schet nakopleniya v kristallicheskoy strukture adsorbenta defektov razlichnogo roda. Bentonit-uglerodnyy kompozit poluchen s ispol'zovaniem roliko-kol'cevoy vibromel'nicy s sootnosheniem ugol'-bentonit 30 : 70 i 50 : 50. O haraktere vzaimodeystviya mezhdu uglem i bentonitom sudili po izmeneniyu poverhnosti i poristosti. Po parametram poristoy struktury obrazcov ustanovleno, chto mehanohimicheskaya aktivaciya smesi soprovozhdaetsya vzaimodeystviem mezhdu komponentami. Izucheny strukturno-himicheskie izmeneniya v processe modifikacii bentonita aktivirovannym uglem s pomosch'yu analiza kolebatel'nyh spektrov uglya, ishodnogo i modificirovannogo obrazcov alyumosilikata. Rezul'taty issledovaniy adsorbentov metodom infrakrasnoy spektroskopii ukazyvayut na poyavlenie polos pogloscheniya, harakternyh dlya kolebaniy svyazey Si-O-S. Issledovana sorbcionnaya sposobnost' mehanohimicheski modificirovannogo aktivirovannym uglem Dash-Salahlinskogo bentonita, prirodnogo glinistogo minerala, po otnosheniyu k tetraciklin gidrohloridu. Izuchena kinetika processa. Pokazano, chto sorbciya tetraciklina idet dostatochno bystro. Vyskazany soobrazheniya o vozmozhnyh mehanizmah protekaniya processa: hemosorbcii za schet donorno-akceptornogo vzaimodeystviya i ionoobmennyh processov.
