摘要: Mesoporous silica nanoparticles (MSN) were synthesized and modified with (3-aminopropyl) triethoxysilane (APTES) using co-condensation (co-MSN) post-grafting (post-MSN) methods. Both modification methods seem to alter the crystallinity, surface area, pore volume as compared unmodified MSN. The activity of all MSNs was tested for adsorptive removal phenol. Co-MSN showed significantly good adsorptivity towards 10 mg L -1 phenols, followed by post-MSN It found that highest co-MSN resulted from additional higher adsorption energy quaternary alkylammonium groups (Si–C–C–C–[N + –(CH 3 ) ]) cationic template also amine group APTES functionalization, which more advantages
