摘要: Many of the factors influencing adsorption volatile organic compounds by activated carbon fibers (ACFs) have been widely studied. However, most them were investigated at low concentrations (500 ppm or less) and temperatures (lower than 100 °C). This study was to determine simultaneously oxidation toluene onto high concentration temperatures. We tested three ACFs, four inlet (700, 1,200, 1,600, 2,000 ppm), (25, 50, 75, 200 The composition morphology ACFs also analyzed using BET, FTIR, EA, FESEM. results indicated that best capacity for 569 mg/g a 1,200 25 °C. A combination O content mesopore volume desirable with concentrations. Moreover, breakthrough time decreased increasing concentration, increased significantly when ppm. data temperature. outlet did not reach saturated °C, as oxygen functional groups on ACF surface had reacted form other compounds.
