In this work the effects of physical and surface properties of polymeric resins on adsorption capacity of phenol were investigated BET surface areas and pore size distributions of the polymeric adsorption resins,NKA Ⅱ(polar resin),AB 8(weak polar resin) ,D4006(weak polar resin) and D16(non polar resin),were separately measured by ASAP 2010M,and isotherms of phenol on the resins were separately estimated by the method of static adsorption Results indicated that the adsorption capacity of NKA Ⅱ resin for phenol in dilute aqueous solution was the highest,and the adsorption capacity of AB 8 resin was in the next place;and the micropore volume and polarity of a polymeric resin showed a strong influence on the adsorption capacity of phenol on the resin Among the four sorts of resin, the adsorption capacity of the NKA Ⅱ resin for phenol was the highest since it is not only polar but also possesses a considerable portion of micropore
CuO/CeO2/γ-Al2O3 catalysts were prepared by both an ultrasound-assisted impregnation method and by a conventional impregnation method. The catalytic combustion of two volatile organic compounds （VOCs）, toluene and benzene, was carried out by using these CuO/CeO2/γ-Al2O3 catalysts. The surface properties of these catalysts were characterized with X-ray diffraction （XRD） and X-ray photoelectron spectroscopy （XPS）. The experimental results showed that the ignition temperature and total conversion temperature of the VOCs on the CuO/CeO2/γ-Al2O3 catalysts prepared by ultrasound-assisted impregnation were much lower than those on the CuO/CeO2/γ-Al2O3 catalysts prepared by conventional impregnation, and the activity of the CuO/CeO2/γ-Al2O3 catalysts prepared by ultrasound-assisted impregnation was much higher than that of the CuO/CeO2/γ-Al2O3 catalysts prepared by conventional impregnation. XRD results showed that the use of ultrasound improved the dispersion of Cu ions on the surface of the CuO/CeO2/γ-Al2O3 catalysts.XPS results indicated that the use of ultrasound promoted the distribution of active components on the surface of the CuO/CeO2/γ-Al2O3 catalysts and increased the Cu+ content on the surface of the catalysts so that the activity of the catalysts for VOCs combustion can be enhanced.
