Abstract
Reactive oxygen species (ROS) can be produced by interactions between sunlight and water, such as photochemically decomposed reaction. These reactive intermediates as strong oxidants could induce the microbial inactivation . This study discusses the effects of solar and different ultraviolet radiation on the microorganisms. Besides, the ROS is generated from excited photocatalyst and photosensitizer by solar or ultraviolet radiation. The ROS photochemistry can be a good potential technology for maintaining the environmental quality.
Keyword: reactive oxygen species, solar, ultraviolet radiation, photocatalyst, photosensitizer
