We report the adsorption equilibrium, kinetics and thermodynamic studies of endo-1,4-β-D-xylanase adsorption onto ordered mesoporous matrices of silica, carbon, and zirconia. Rapid adsorption of the enzyme was observed within 5 min, and the equilibrium was attained in 60 min. The adsorption profiles were fitted to a pseudo-second-order kinetic equation indicating a tendency towards chemisorption and that the kinetics improved with temperature. Besides, it was found that the adsorption equilibrium data followed a typical Langmuir model and that the activation energy was determined using the Arrhenius equation. Likewise, the computed thermodynamic parameters revealed that the adsorption is favourable, spontaneous, and endothermic.
