摘　　要：文章对4-氯酚在非均相零价铁/H2O2体系中的降解进行了实验研究。结果表明,4-氯酚能在低pH零价铁/H2O2体系中迅速降解。pH对降解具有重要影响,当pH大于5,4-CP降解效果<10%。同时在低pH(pH3)环境下考察了铁粉和H2O2投加量的影响,在最佳条件下对溶液中亚铁离子的形成和过氧化氢的分解进行了进一步的实验研究。最后在对中间产物分析的基础上提出了4-CP降解路径假设。Experiment was done for 4-CP degradation in ZVI/H2O2 system. Results showed that 4-CP can be rapidly degraded in low pH ZVI/H2O2 system, pH had great impact on the degradation efficiency, with degradation efficiency, less than 10% at pH above 5. Addition of iron powder and H2O2 at pH3 was investigated, and degradation path of 4-CP was proposed based on analysis of intermediates.
