项目摘要
9414594 Pignatello This is an award to provide support for research on an advanced oxidation process for destruction of organic contaminants of water and soil. The process involves use of iron in the ferric state, near-ultraviolet light radiation and hydrogen peroxide. The objectives of this research are to study key features of the inorganic and photochemical mechanisms that affect oxidation of the target organic compounds and the applications of this innovative environmental technology. The investigator plans on determining whether a hypervalent iron-oxo complex is formed photochemically that supplements the action of the hydroxyl radical in oxidation of organic compounds and expects to clarify the role of ferric iron in this reaction. The applications phase of this research will address the effect of light intensity and temperature on the reaction rate, the kinetics and pathways of degradation of organic substances subjected to the process, the influence of common anions on the reaction rate and the feasibility of a two stage system combining this advanced oxidation process with a biological process for treatment of water and soil contaminated with organic wood preservatives. Results of this project are expected to provide the basis for considering its use in treatment of soil and water that has been contaminated with organic substances of commercial, industrial and agricultural significance. ***
9414594 Pignatello这是一个奖项,为先进的氧化过程破坏水和土壤中的有机污染物的研究提供支持。 该过程涉及使用三价铁、近紫外线辐射和过氧化氢。 本研究的目的是研究影响目标有机化合物氧化的无机和光化学机制的关键特征以及这种创新环境技术的应用。 研究人员计划确定是否形成了一种高价铁-氧代络合物,以补充羟基自由基在有机化合物氧化中的作用,并希望澄清三价铁在该反应中的作用。 这项研究的应用阶段将解决光强度和温度对反应速率的影响,有机物质降解的动力学和途径,研究了常见阴离子对反应速率的影响,探讨了该高级氧化工艺与生物工艺相结合的两级系统处理有机木材污染水和土壤的可行性防腐剂. 预计该项目的结果将为考虑将其用于处理被具有商业、工业和农业重要性的有机物质污染的土壤和水提供依据。 ***
