Abstract:		"Volatile organic compounds (VOCs), which are usually organic compounds with boiling point in the range of 50 to 260 degrees C, pose a serious threat to human health and ecological environment. In order to find an adsorbent with excellent adsorption effect on VOCs, activated carbon was prepared from corn bran partially degraded by Trichoderma viride, and the adsorption performance of the optimized porous carbon materials on toluene was studied. Physical and chemical properties (such as specific surface area, pore size distribution, and surface functional groups) of the activated carbon were characterized by scanning electron microscope (SEM), N(2) adsorption/desorption experiences, Fourier-transform infrared (FTIR), and Raman and X-ray diffraction (XRD). The results showed that the specific surface area of corn bran reached 1896 m(2)/g and the total pore volume was 1.04 cm(3)/g after 15 days of microbial pretreatment. Dynamic simulation of adsorption experiment found that the saturated adsorption capacity of the pretreated carbon material was 237 mg/g at 100 ppm toluene concentration, which was 1.58 times of that of corn bran without microbial pretreatment. Generally, the improvement of adsorption performance may be mainly attributed to the increase of specific surface area, pore volume and the decrease of surface acidic groups"
