WebPhotodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by photons.It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light.Any photon with sufficient energy can … WebTotal cyanide species are determined in a flow injection system which includes UV-photodissociation, gas-diffusion separation and spectrofluorimetric detection. Without the irradiation step, only cyanide easily released in acid medium, i.e. labile cyanide, is determined.
