Abstract：This study is to explore adsorption of modified mesoporous carbon on contaminants in drinking water,and the experiment was conducted to improve the adsorption performance of mesoporous carbon through combining ordered mesoporous carbon with ferric-chloride,manganese oxide or the adsorption efficiency of three indexs such as sulfide,dichloroacetic acid or Escherichia coli and the effects of time,adsorbent dosage were studied.It was found that the modified materials are better than mesoporous carbon in different conditions,only except OMC-MnO in the adsorption of sulfide.Also,it turns out that mesoporous carbon can remove 98.6％ of sulfide from the mixed solution of sulfide,dichloroacetic acid and Escherichia coli.The removal rate can reach up to 99.98％ and 99.73％ while mesoporous carbon was replaced by OMC-Fe and OMC-MnO.For dichloroacetic acid,the removal rate is 43.62％(mesoporous carbon),45.37％(OMC-Fe) and 44.92％(OMC-MnO).According to the result of research,modified mesoporous carbon ought to adsorb 5％ Escherichia coli more than mesoporous carbon's 90％,modified mesoporous carbon has an excellent advantage.
