Abstract: The kinetics of the degradation of nitro phenol isomers (2-nitrophenol, 3-nitrophenol, 4-nitrophenol) with the hydrogen peroxide photolysis, photo-Fenton and photocatalysis was investigated. The efficiency for the studied treatments were evaluated and compared. The Fenton reagent was found to be the most efficient way for the nitrophenols (NPs) degradation. The degradation of the organic compounds was determined spectrophotome trically and TOC can be identified by standard COD determination method. The degradation and detoxification of the processes have been found to adhere first order kinetics. As per refractory nature of nitrophenols the order of their mineralization was found as 4-NP>2-NP>3-NP. All the degradation processes were carried out in a batch photo reactor.
