摘要：
The adsorption of lysozyme and trypsin by the mesoporous materials MCM-41 and SBA-15 with different pore volumes has been studied as a model protein adsorption system. The amounts adsorbed depend on the pore volumes and surface chemistry of the mesoporous materials as well as the binding mechanisms of particular proteins. The adsorbed amounts of lysozyme on MCM-41 were 90-110 mg/g over a wide range of lysozyme solution concentrations, whereas the adsorption isotherm of trypsin on MCM-41 fitted the Langmuir model and adsorbed amounts of up to 200 mg/g were recorded.
