AlOOH催化臭氧氧化降解愈创木酚的研究
Study on Degradation of Guaiacol by Catalytic Ozonation Using AlOOH as Catalyst
摘要
Abstract
AlOOH was chosen as catalyst for ozonation of guaiacol,the model compound of lignin.A series of experiments were conducted to investigate the influence of oxidation condition on the degradation of guaiacol and CODcr removal efficiency,such as the kind of catalyst,ozone flow rate,initial pH value of reaction system and catalyst dosage.The reaction mechanism was preliminary studied by liquid chromatography analysis and addition of hydroxyl radical scavenger tea-butyl alcohol (TBA).The results showed that compared with sole ozonation,catalytic ozonation could improve the efficiencies of guaiacol degradation and CODCr removal.The degradation rate of guaiacol (200 mg/L)reached 100％ and the CODCr removal efficiency was 89.3％ after 40 min reaction at pH value of 5.4 when the ozone concentration,ozone flow rate,and the dosage of AlOOH were 13.32 mg/L,0.51 L/min and 5 g/L,respectively.Both hydroxyl radical and O3 played an important role on the degradation process of guaiacol.关键词
