| 摘 要： | 采用溶剂热法制备介孔聚二乙烯基苯(PDVB)树脂,并以介孔分子筛MCM-41、SBA-15为参照,从吸附-脱附甲苯、邻二甲苯、均三甲苯性能和高湿度下的疏水性能方面对其进行对比研究.结果表明,PDVB具有最大的比表面积1219.1m2/g,其对低浓度甲苯吸附量约为介孔分子筛的2倍,同时吸附性能几乎不受水汽影响.随着VOCs分子尺寸增加,3种吸附剂对VOCs的饱和吸附量均有所增加,但PDVB的穿透吸附量明显高于分子筛.热重分析表明,在200℃以下3种吸附剂上吸附的有机分子均能脱附完全,具有优良的脱附再生性能. |

| Abstract: | Polydivinylbenzene(PDVB) resin with mesopore was synthesized by solvothermal method.Its hydrophobicity in high humidity and adsorption-desorption of toluene,o-xylene and mesitylene were investigated,and were compared with those of the mesoporous molecular sieves(MCM-41 and SBA-15).PDVB resin had a maximum surface area of 1219.1 m2/g.The adsorption capacity of toluene on PDVB was about twice as that of the mesoporous molecular sieves.Furthermore,its adsorption property was not affected by the presence of water vapour.For the three adsorbents tested,the amount of typical VOCs adsorbed increased with the increasing of the sizes of VOCs molecules.The breakthrough adsorption capacity of VOCs on PDVB was significantly higher than that of the mesoporous materials.TGA results showed that the adsorbed VOCs on all three adsorbents desorbed completely below 200℃,demonstrating their good desorption property. |
| Keywords: | PDVB mesoporous molecular sieve VOCs adsorption/desorption |
