General description

2-Chloroaniline is widely used in polymer, rubber, pharmaceutical and dye industries. Determination of 2-chloroaniline in polymer industrial wastewater has been examined using HPLC with on-line microdialysis. Degradation of 2-chloroaniline in water by ozonation as well as by photolysis (UV-light of 254 nm) and radiolysis (γ-rays) in the presence of ozone has been investigated.
