In water treatment, ultraviolet irradiation, ozonation, and chlorination are believed to produce various active oxygen species, which seem to participate in reactions with fumic acid, pollutants and bacteria. It was, however, very difficult to determ

Identification of the species of active oxygen generated in water by chlorination or ozonation was carried out by the spin trapping method using DMPO as the spin trap agent with ESR spectrometry. On chlorinating with NaOCl solution (15 mg/litre), typ
