Has been presented the data on laevomycetin absorption from aqueous solution in static and dynamic conditions on industrial active carbons AG‑5 and BAU-A in a wide range of concentrations. It has been shown that the calculation of adsorption’s equilibrium value and process duration at the concentration of 25–200 mg·dm–3 with sufficient accuracy can be performed using Dubinin–Radushkevich–Astakhov and Dubinin–Nikolaev equations respectively. Have been proposed equations for levomycetin adsorption value calculation depending on the carbons’ micropores volume, as well as for a characteristic energy depending on the pores size.
adsorption, micro- pores, mesopores, characteristic energy, isotherm equations, laevomycetin (chloramphenicol), wastewater, mass transfer coefficient.
1. Введение в проблему
К опасным загрязняющим веществам (ЗВ), характерным для сточных вод фармацевтических предприятий, относятся антибиотики. В настоящее время для очистки сточных вод от антибиотиков, находящихся во взвешенном состоянии, предлагается ряд методов и способов, из которых наиболее известны мембранные технологии (ультра- и гиперфильтрационные, электрохимические) [1, 2].
