Application of Fenton's reagent as a pretreatment step in biological degradation of polyaromatic hydrocarbons

摘要: Fenton's reagent (H{sub 2}O{sub 2} and Fe{sup ++}) has been used for chemical oxidation of numerous organic compounds in water treatment schemes. In this study, the Institute Gas Technology (IGT) applied to polynuclear aromatic hydrocarbons (PAHs) PAH-contaminated soils. was very reactive with PAHs, causing rapid modification parental oxidized products complete degradation CO{sub 2}. This more effective on chemically such as benzo(a)pyrene phenanthrene. Important parameters conditions PAHs solution soil matrices have identified. As much 99% can be removed by reagent. 28 refs., 13 figs., 1 tab.
