Abstract: Adsorption of trichlorethylene from aqueous solutions by activated carbons of various grades was studied previously under static conditions [6]. We carried out a comprehensive study of the trichlorethylene adsorption process in the presence of chloroform by carbon sorbents, including the study of equilibrium, kinetics, and adsorption process dynamics in order to create an adsorption technology for purifying natural waters from organic compounds. The aim of the study was to establish the mass transfer mechanism and obtaining the mass transfer coefficients required for engineering calculations, using various models that describe the kinetics of sorption extraction. The kinetic parameters of sorption process are influenced by various factors, including specific surface area, carbon sorbents' structure, and conditions for the transfer of adsorbed substance molecules to the grain surface of adsorbent. So, as a result, calculated coefficients of external mass transfer allow us to expect a high rate of the component extraction from the water to be purified by filtering through a a fixed sorbent layer of the AC grades: SCLF-515, AG-WV-1, PPS, Purolat-standard.
