摘要

以工业废渣（硼石膏）为吸附剂，通过高压灭菌法处理，研究了无盐背景的氯化钴水溶液中Co2+离子的吸附动力学和扩散参数。在20、40和60℃的温度下，得到了Co2+离子吸附的动力学曲线，并使用化学动力学模型进行了分析。在选定的温度条件下，确定了标准焓（ΔH°）、标准熵（ΔS°）、标准自由能（ΔG°）、Co2+离子扩散系数等热力学参数。

Kinetic and Diffusion Parameters of the Sorption of Co2+ Ions by a Sorbent Based on Industrial Waste

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.
