活性炭对2,4-二氯苯酚的催化臭氧化降解

摘要

Ozonation treatment of 2,4-dichlorophenol (2,4-DCP) with granular activated carbon (GAC) in a fluid bed reactor was investigated, and enhanced 2,4-DCP decomposition was obtained when GAC amount increased. Higher efficiency of catalytic ozonation could be achieved in acid pH, but the influence of the strength of acid and basic pH could be neglected. The results of repeated use showed that GAC could be efficiently regenerated in situ in the reactor and maintain its high activity.%研究了粒状活性炭(GAC)对2,4-二氯苯酚(2,4-DCP)臭氧化降解的催化性能.由于活性炭的吸附和催化作用,提高了2,4-DCP的分解.在酸性条件下具有较高的催化臭氧化效率,而酸性和碱性的强弱对2,4-DCP的分解几乎没有影响.活性炭的重复使用实验表明活性炭在臭氧化处理过程中可以得到原位再生,多次使用后其催化活性几乎没有降低.
