摘要：In this study, Fenton reagent has been adopted to oxidize and regenerate the resin based spherical activated carbon (SAC) adsorbed with toluene saturation. The effects of the mole ratio of Fe(2+)and H2O2, the dosage of H2O2, pH value, temperature, regeneration time and the like on the regeneration rate of activated carbon have been exploited, the adsorbent used in the experiment is spherical activated carbon with a maximum adsorption capacity of 512.25 mg/g produced by Cui hong Taiyuan Science and Technology Co. The results show that the highest regeneration rate of activated carbon can reach 95.69%. The optimal regeneration condition is that the molar ratio of Fe(2+)and H(2)O(2)is 1/25, the concentration of H(2)O(2)is 175 mmol/L, the pH is 2, the temperature is 20celcius similar to 30celcius, and the regeneration time is 180 min. The influence of regeneration process on the characterization of activated carbon has been studied by BET analysis as well as SEM analysis.
