基于微波放电无极灯(MDEL)的新型光源被认为是驱动光化学过程的潜在光源，特别是高级氧化过程(AOPS)，描述了其各种应用。MDELs具有几个特点，使其成为可能的环境修复灯和光源，以激活环境修复过程中的金属氧化物光催化剂。因此，这篇文章描述了MDEL设备的许多特征中的一些，尽管不是详尽的，并报告了一些包含这些MDEL的光反应器。介绍了MDEL光源在实际污染物修复处理中的基本问题。这些例子包括氧化破坏挥发性有机化合物(挥发性有机化合物；例如乙醛和甲苯)、氧化降解废水中存在的污染物(例如2，4-D除草剂和内分泌干扰剂双酚A)和修复受二恶英污染的飞灰，以及水泥生产的实际工业废水样本。
Novel light sources based on microwave discharge electrodeless lamps (MDEL) are examined as potential light sources to drive photochemical processes, in particular advanced oxidation processes (AOPs) of which various applications are described. The MDELs possess several features that make them attractive as possible environmental remediation lamps and as light sources to activate metal oxide photocatalysts in environmental remediation processes. Accordingly, the article describes some of the many features, albeit non-exhaustively, of MDEL devices and reports some photoreactors that incorporate these MDELs. Fundamental issues of MDEL light sources in remediation processing of actual pollutants are introduced. Examples are taken from the oxidative destruction of volatile organic compounds (VOCs; e.g. acetaldehyde and toluene), from the oxidative degradation of contaminants present in wastewaters ( e.g. the 2,4-D herbicide and the endocrine disruptor bisphenol-A) and from the remediation of dioxin-contaminated fly-ash, along with an actual industrial wastewater sample from the manufacturing of cement.
