| Abstract: | Catalytic degradation process for the congo red was investigated by using the Fe-pillared bentonite as catalyst and adsorbent,and H2O2 as oxidant.The experimental results indicated that the disadvantages of Fenton reagent were eliminated by the Fe-pillared bentonite,and the degradation ratio of congo red reached 91% under the following conditions: pH value was 3,reaction temperature was 75,dosage of H2O2 was 0.016 mol/L,dosage of bentonite was 0.4 g/L,reaction time was 30min. |
