摘要

The thermodynamics and kinetics behavior of 2-keto-L-gulonic acid in aqueous solution by D02 resin have been investigated. The analysis of adsorption results obtained at 298.15 K, 308.15 K and 318.15 K showed that the adsorption pattern on D02 resin followed the Langmuir isotherms. Thermodynamic parameters such as ΔH, ΔG and ΔS were calculated from the slope of the linear plot of ln(1/C_e) against 1/T. The ΔH and ΔG values of 2-keto-L-gulonic acid adsorption on D02 resin showed endothermic heat of adsorption; higher temperatures favor the process. The kinetics experiments showed that the particle diffusion was the rate-controlling step and furthermore the diffusion coefficient was calculated.
