摘　　要：铁氧化物(IOs)和草酸非均相光化学体系作为传统Fenton和非均相Fenton法的进一步拓展,有助于激发矿物的潜在本能,发挥天然自净化的优势,改善日益严重的水体污染问题。然而自然界中IOs种类繁多且各有差异,导致各IOs-草酸光化学体系降解性能也存在不同。在总结IOs结构性质的基础上,对比了不同IOs-草酸光化学体系的降解性能,并从草酸吸附、铁溶出、活性氧物种生成3个方面对体系光化学机理差异进一步展开论述,同时对后续研究做出展望,旨在通过调控IOs自身性质,打造出行之有效、性能更强的新模式。As a further extension of the traditional Fenton processes and non-homogeneous Fenton processes,iron oxides(IOs)and oxalic acid non-homogeneous photochemical systems could stimulate the potential instincts of minerals to take advantage of natural self-purification and ameliorate the growing problem of water pollution.However,in nature,there are many types of IOs and each has its own differences,resulting in different degradation performance of various IOs-oxalic acid photochemical system.On the basis of summarizing the structural properties of IOs,the degradation performance of different IOs-oxalic acid photochemical system was compared,and the differences in the photochemical mechanisms of the systems were further discussed from three aspects(oxalic acid adsorption,iron solubilization,and generation of reactive oxygen species).At the same time,prospects were made for future research,aiming to create an effective and stronger new mode of transportation by regulating the properties of IOs themselves.
