卤代芳烃类有机物是一类在环境中分布极其广泛,且对生物体具有强致癌性的一类物质.近年来,这类物质因其可能导致对人体健康以及生态系统的潜在环境风险而被公众日益关注.高级氧化过程(AOPs)作为一种“环境友好”的技术被越来越多地用于对这类高毒性且难降解有机物污染的土壤或水体进行修复.在最近的研究中,我们发现由高级氧化介导的持久性有机污染物如五氯酚以及其它卤代芳烃的降解过程中会产生内源性的化学发光,并且这种内源性的化学发光直接依赖于该过程中产生的极具活性的羟基自由基(·OH).我们认为该反应过程中生成了某种依赖于·OH形成的醌中间体以及激发态多羰基产物,正是它们导致了这种不同寻常的化学发光.在上述研究基础上,进一步开发出一种快速灵敏且简单有效的化学发光分析手段用于定量检测痕量的卤代芳烃,并将其成功应用于这些持久性有机污染物降解动力学的实时监测.
Halogenated aromatic hydrocarbons are a group of substances that are extremely widespread in the environment and have a strong carcinogenic effect on the organism, which in recent years has been used for its potential environmental risks to human health and to ecosystems The public is increasingly concerned that advanced oxidation processes (AOPs) are being increasingly used as an “environmentally friendly” technology to repair soils or bodies of water that are contaminated with such highly toxic and refractory organics.In a recent study , We found that endogenous chemiluminescence was produced during the degradation of advanced oxidatively-mediated persistent organic pollutants such as pentachlorophenol and other halogenated aromatics, and that this endogenous chemiluminescence was directly dependent on the (· OH) .We think that some of these quinone intermediates and excited-state polycarbonyl products that are dependent on the formation of · OH are formed during the reaction, which is why they lead to this difference Based on the above research, we developed a fast, sensitive and simple and effective chemiluminescence analysis method for the quantitative detection of trace amounts of halogenated aromatic hydrocarbons and their successful These persistent organic pollutants in real-time monitoring of the degradation kinetics.
