Advanced Oxidation Processes (AOPs) – Utilization of Hydroxyl Radical and Singlet Oxygen

Considering the nature of organic contaminants in water, methods their oxidative decomposition seem to be most appropriate for removal from contaminated water. There are a lot chemical oxidation, however, Advanced Oxidation Processes (AOPs) suitable technologies removal. AOPs belong group processes that efficiently oxidize compounds towards harmless inorganic products such as water or carbon dioxide. The have shown great potential treatment pollutants low high concentrations and found applications various types contamination. hydroxyl radical (•OH) is oxidizing agent used at drive contaminant decomposition. It powerful, non-selective oxidant, which reacts very rapidly with compounds. Another strong agent, singlet oxygen, can generated by photosensitization phthalocyanines. Phthalocyanines molecules based on pyrrol structures connected mainly methionine groups (–CH=) having metallic central atom. Illumination upon specific wavelengths initiates formation oxygen attack contaminants.
