| 摘 要： | 以活性炭为催化剂，H2O2作氧化剂催化氧化降解对氯硝基苯(PCNB)，结果表明，在H2O2／CODcr=1．2，活性炭／H2O2=0．4，pH=3．0的条件下，反应可在180min结束，PCNB的去除率高于99％，CODcr去除率可达80％，与Fenton试剂法相比较，CODcr去除率提高1．78倍，并对降解机理作了初步讨论。

| Abstract: | Catalytic oxidation process for the PNCB degradation was taken with activated carbon of catalyst and H 2O 2 of oxidant.The study shows that the degradation reaction completed within 180 minutes with over 99% of PNCB removal and COD Cr removal under the conditions of H 2O 2/COD Cr=1.2,carbon/H 2O 2=0.4,pH=3.0.This is improved to be 1.78 times of the COD Cr removal obtained by Fenton method.The paper also discussed preliminarily the degradation mechanism. |
