摘　　要：水热晶化法制备介孔硅MCM-41。采用电子自旋共振法评价负载角鲨烯介孔硅对卷烟烟气中自由基清除效果。当卷烟滤嘴中添加负载3 mg角鲨烯的20 mg MCM-41,对卷烟烟气中气相自由基的清除率为31.55%,固相自由基的清除率为36.85%,分别优于添加20 mg MCM-41的清除率为4.14%和14.92%。Mesoporous silica MCM-41 was synthesized by hydrothermal crystallization. The scavenging effects against free radicals in mainstream cigarette smoke were evaluated by Electron Spin Resonance(ESR) Spectroscopy. Twenty mg MCM-41 loaded 3 mg squalene/filter treatment showed the highest scavenging effects against gas-and particulate-phase free radicals were 31.55 % and 36.85 %;20 mg MCM-41/filter treatment were 4.14 % and 14.92 %, respectively.
