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.
