photolysis
의미: The decomposition or dissociation of a chemical compound by the action of light, especially ultraviolet radiation.
Photolysis is a key process in atmospheric chemistry, where ultraviolet light breaks apart ozone and other molecules, and in photosynthesis, where light energy splits water molecules to release oxygen. 'Photolysis of water,' 'photolysis reaction,' and 'UV photolysis' are standard collocations. In environmental science, photolysis is one of the main pathways by which pollutants and pesticides are broken down in the atmosphere. The process is also exploited in water treatment to destroy harmful microorganisms.
