Abstract
The present work investigated the adsorption behaviors of lysozyme onto weak cation exchangers at different temperatures. The adsorption isotherm, adsorption thermodynamics and adsorption kinetics were studied. The results indicate that the adsorption of lysozyme onto acrylic acid copolymer based beads (Hydrolite D115) is spontaneous and exothermic, while that onto agarose based beads (CM Sepharose 6 Fast Flow) is also spontaneous, but endothermic. The pseudo second-order kinetic model fits well to the dynamic adsorption experimental data, and the kinetic results are also in concert with the adsorption thermodynamics.
