| description | Hypercrosslinked polymers(HCPs) were prepared by cashew nut shell liquid(CNSL), an agricultural by-product, as a raw material, using external cross-linker method and solvent cross-linker method, and named F-HCP and C-HCP, respectively. The adsorption properties of volatile organic compounds(VOCs) on F-HCP and C-HCP were investigated. The prepared adsorbent was characterized by infrared spectroscopy(FTIR), thermogravimetric analysis(TGA), N2 adsorption and scanning electron microscopy(SEM). The adsorption properties of six kinds of VOCs on F-HCP and C-HCP were investigated by static adsorption method. The o-xylene was used as a typical VOC for dynamic adsorption, and the influence of inlet concentration on adsorption was investigated. The results show that F-HCP has higher static adsorption performance than C-HCP, and the static adsorption capacities of o-xylene, toluene, cyclohexane, n-hexane, methyl ethyl ketone, and acetone on F-HCP are 930, 801, 300, 214, 203 mg·g-1and 164 mg·g-1, respectively. At the inlet concentration of 2171 mg·m-3 for o-xylene, the dynamic adsorption capacity of F-HCP and C-HCP for o-xylene is 149 mg·g-1 and 146 mg·g-1, respectively. The equilibrium adsorption capacity increases with the increase of the inlet gas concentration. The cyclic regeneration adsorption experiments indicate that the adsorption capacity of C-HCP after five cycles of adsorption is 93.9% of the first adsorption capacity. |
