Ecological Systems and Devices Annotation << Back STUDYING OF PHYSICAL AND CHEMICAL PARAMETERS OF PROCESS OF ADSORPTION OF CARBOXYMETHYLCELLULOSE MOULDING OF THE ASTRAKHAN REGION E.Yu. Shachneva, V.Ya. Khentov The key physical and chemical parameters of adsorption of high-molecular connection (carboxymethylcellulose) on a natural mineral sorbent – a molding of the Astrakhan region are studied. Isotherms of static sorption of a component are constructed of water solutions. The main thermodynamic characteristics of sorption processes are defined: change of an enthalpy (ΔH), isobaric and isothermal potential (ΔG) and entropy (ΔS) of sorption. The kinetics of sorption of carboxymethylcellulose from water solutions is considered. The possibility of sewage treatment from the considered component with application of a molding of the Astrakhan region is studied. The possible way of purifi cation of model solutions of sewage by method of a fractional fl okulirovaniye with use of carboxymethylcellulose is presented. Keywords: physical and chemical parameters of adsorption; carboxymethylcellulose; molding of the Astrakhan region; thermodynamic parameters; kinetic parameters; cleaning; method of fractional fl occulation.
