| 英文摘要 | dibenzodioxin adsorption/desorption on solid surfaces is an important issue associated with the formation, adsorption, and emission of dioxins. dibenzodioxin adsorption/desorption behaviors on inorganic materials (amorphous/mesoporous silica, metal oxides, and zeolites) were investigated using in situ ft-ir spectroscopy and thermogravimetric (tg) analysis. desorption temperatures of adsorbed dibenzodioxin are very different for different kinds of inorganic materials: similar to 200 degrees c for amorphous/mesoporous silica, similar to 230 degrees c for metal oxides, and similar to 450 degrees c for nay and mordenite zeolites. the adsorption of dibenzodioxin can be grouped into three categories according to the red shifts of the ir band at 1496 cm(-1) of the aromatic ring for the adsorbed dibenzodioxin: a shift of 6 cm-1 for amorphous/mesoporous silica, a shift of 10 cm(-1) for metal oxides, and a shift of 14 cm(-1) for nay and mordenite, suggesting that the ir shifts are proposed to associated with the strength of the interaction between adsorbed dibenzodioxin and the inorganic materials. it is proposed that the dibenzodioxin adsorption is mainly via the following three interactions: hydrogen bonding with the surface hydroxyl groups on amorphous/mesoporous silica, complexation with lewis acid sites on metal oxides, and confinement effect of pores of mordenite and nay with pore size close to the molecular size of dibenzodioxin. |
