类Fenton试剂氧化降解土壤中PAHs及其影响因素研究
Study on characteristics and influencing factors of PAHs degradation in soil by Fenton-like reagent
摘要
Abstract
Fenton-like reagent could be effectively used for degradation of polycyclic aromatic hydrocarbons（PAHs） in soil.Phenanthrene,pyrene,benzo [a]pyrene and indeno（1,2,3-cd） pyrene were used to study the effects of different factors for the PAHs degradation by Fenton-like reagent.The results showed that the efficient degradation of PAHs in soil by Fenton-like reagent could be achieved under the condition of 0.5 mol/L H2O2 and 0.1 mol/L Fe（NO3）3 in 30 min,with a water-soil ratio of 3∶ 1 and 0.5 mol/L HPCD as catalyst.Among the four types of cyclodextrins,mainly including β-cyclodextrin（β-CD）,hydroxypropyl-β-cyclodextrin（HPCD）,methyl-β-cyclodextrin（MCD） and acetyl-β-cyclodextrin（ACD）,HPCD had the strongest stimulated effect for the oxidation of PAHs in soil by the Fenton-like reagent.关键词
