Rapid and High-capacity Adsorption of Glucose Oxidase on Amine-functionalized Mesoporous Silica SBA-15 Platelets
We have synthesized platelet-like SBA-15 particles and functionalized their surfaces with amine groups for use as adsorbent materials in glucose oxidase (GOD) adsorption. The amine-functionalized SBA-15 exhibits very rapid (<20 min to reach equilibrium) and high-capacity (up to 680 mg g(-1)) adsorption of GOD. It is found that electrostatic interaction is the dominant driving force for GOD adsorption on these mesoporous materials.
