摘要: 2-Anthraquinone sulfonate (2-AQS) was found to exhibit an abnormally high singlet-oxygen quantum yield in aqueous solution after UVA irradiation based on a widely used testing method for singlet oxygen. To discover the cause of abnormal results, several possible reactive oxygen species were also measured system. Results revealed that 2-AQS and two other similar compounds produced oxygen, hydroxyl radicals, superoxide, so-called (ROS), under exposure. The production radical contributed yield. Quantifications ROS by these conducted oxidation p-nitrosodimethylaninline presence absence either l-histidine or superoxide dismutase. EPR results confirmed formation irradiation. influence different exposure times all three photosensitive compounds. effects differe...
