Abstract

A sorbent based on industrial waste (borogypsum), obtained via autoclave treatment, is used to study the kinetic and diffusion parameters of the sorption of Co2+ ions from aqueous solutions of cobalt chloride with no salt background. Kinetic curves of the sorption of Co2+ ions are obtained and analyzed using models of chemical kinetics at temperatures 20, 40, and 60°C. Such thermodynamic parameters as standard enthalpy (ΔH°), standard entropy (ΔS°), standard free energy (ΔG°), and coefficients of Co2+ ions diffusion are determined at selected temperature conditions.
