The oxidative removal of dibenzothiophene adsorbed on activated carbon surface by hydrogen peroxide catalyzed by activated carbon itself was investigated.The regeneration performance of catalytic oxidation on the activated carbon by H2O2 solution,H2O2+HCOOH solution and H2O2+CH3COOH solution was compared firstly.Then the effect of catalysis condition on the activated carbon regeneration performance was studied.The results showed that all three catalytic oxidation methods could regenerate the used activated carbon to some extent.The regeneration performance was the best,reaching above 90% by using H2O2+HCOOH solution.H2O2 concentration,HCOOH concentration,reaction temperature and time affected the regeneration performance of activated carbon when using H2O2+HCOOH solution.The catalysis condition could be optimized to get high regeneration performance.
