Photocatalytic processes in the presence of titanium dioxide provide an interesting route to destroy hazardous organic contaminants, being operational in the UV-A domain with a potential use of solar radiation. In this paper, some specific contaminant classes of interest such as ethylbenzene, gamma-lindane and EPTC have been tested at laboratory scale and in the field to determine the feasibility of the photocatalytic oxidation of organic contaminants in water. Our preliminary results at laboratory scale with these chemicals have provided a better understanding of the photocatalytic process which seems to be efficient and not selective. The application of these processes in removal of gamma-lindane from water operating in a parabolic trough concentrator has demonstrated to be effective, being possible to reduce 99.9% of gamma-lindane levels in water in acceptable times.
在二氧化钛存在的情况下，光催化过程为破坏有害有机污染物提供了一条有趣的途径，它在UV-A波段运行，具有利用太阳辐射的潜力。在本文中，一些特定的感兴趣的污染物类别，如乙苯、γ-林丹和扑草净，已在实验室规模和实地进行测试，以确定水中有机污染物光催化氧化的可行性。我们在实验室规模下对这些化学物质的初步结果，让我们对光催化过程有了更好的理解，该过程似乎高效且无选择性。这些过程应用于在抛物槽式聚光器中运行以从水中去除γ-林丹，已证明是有效的，能够在可接受的时间内将水中γ-林丹水平降低99.9%。
