About this Research Topic
Environment protection is a widely concerned problem in human society. With the rapid development of the world economy, high concentrations of organic wastewater pose a threat to human's precious water resources. It is difficult to treat organics with poor biodegradability and relative molecular weights, ranging from thousands to tens of thousands, by using existing biological treatment methods. Advanced Oxidation Processes (AOPs) can directly mineralize or improve the biodegradability of organic pollutants through reactive oxygen species (ROSs). In addition, AOPs have great advantages for the treatment of trace harmful chemicals such as environmental hormones, enabling complete mineralization or decomposition of most organic materials. Furthermore, AOPs have good application prospects.
AOPs, also called deep oxidation technologies, are characterized by the generation of ROSs such as a hydroxyl radical (·OH) with a strong oxidation ability. Under the reaction conditions (high temperature and high pressure, electricity, ultrasound, light irradiation, catalyst, etc.) organic matter with large molecules can be oxidized into low toxic or non-toxic smaller molecules. According to the different ways of generating free radicals and reaction conditions, AOPs can be divided into photocatalytic oxidation, catalytic oxidation, acoustic chemical oxidation, ozone oxidation, electrochemical oxidation, Fenton oxidation, etc. This Research Topic, therefore, welcomes articles on the following themes:
• Fenton or Fenton-like reactions for environmental remediation
• Catalytic oxidation technologies, including photocatalysis and electrocatalysis, for pollutant control
• Studies on free radical and non-free radical mechanism in AOPs reactions
• Analysis and monitoring of pollutants in AOPs, as well as the mechanism of pollutant digestion
Keywords: Advanced Oxidation Process, Fenton, Catalytic oxidation, Reactive Oxygen Species, Pollutant control
