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.

The environmental analysis of amines is important to preserve human health because these compounds often have toxic effects. Gas chromatography (GC) of free amines is generally unsatisfactory owing to the adsorption and decomposition of the solutes on the column. Derivatization
