KINETIC AND DIFFUSION PARAMETERS OF SORPTION OF Co IONS BY SORBENT BASED ON INDUSTRIAL WASTE

Kinetic and diffusion parameters of sorption of Co ions under static conditions from aqueous solutions of cobalt chloride without salt background by a sorbent based on industrial waste (borogypsum) obtained by their autoclave treatment are studied. Kinetic curves of sorption of Co ions at temperatures from 20, 40, and 60°C are obtained and analyzed by chemical kinetics models. Thermodynamic parameters such as the standard enthalpy (∆H), standard entropy (∆S), and standard free energy (∆G) are calculated. The diffusion coefficients of Co ions in selected temperature modes are determined.
