Self-sensitized photodegradation of benzisothiazolinone by low-pressure UV-C irradiation: Kinetics, mechanisms, and the effect of media

Benzisothiazolinone (BIT) is a kind of non-oxidizing biocide widely used in reverse osmosis process for wastewater reclamation. Most BIT would reside in the RO (reverse osmosis) concentrates and show adverse effects on aquatic life when it is discharged into surface water. This study analyzed the photodegradation of BIT under UVC (254 nm) irradiation and found that UVC irradiation was as an efficient way to degrade BIT, of which the process...
