- ... Mesoporous sieves MCM-41 modified by trimethylchlorosilane and methyltrimethoxysilane were prepared by postsynthesis grafting (PSG) process and further characterized by thermogravimetric (TG) analysis, FTIR spectroscopy, and nitrogen sorption experiments. Adsorption experiments of phenol and hydroquinone in solutions were carried out. The surface properties of silica were found to be the key facto ...
