Abstract

The adsorption of cytochrome c onto different mesoporous molecular sieves (C12−MCM-41, C16−MCM-41 and SBA-15) is studied at different solution pHs. Adsorption isotherms were recorded up to final solution concentrations of ca. 250 μmol/L and were found to be of the pseudo-Langmuir type. Cytochrome c ...
