Abstract

A dynamic kinetic model for the oxidation of phenol in water by an UV/H~2~O~2~ process is developed. The model is based on the elementary chemical and photochemical reactions, initiated by the photolysis of hydrogen peroxide into hydroxyl radicals. The model is validated by using experimental data obtained from the open literature for an actual UV/H~2~O~2~ process. Using those data and the developed kinetic model, kinetic rate constants for phenol intermediates, catechol and hydroquinone, are estimated. Moreover, the optimum initial hydrogen peroxide concentration is estimated by means of the validated model. © 2007 Wiley Periodicals, Inc. Int J Chem Kinet 40: 34–43, 2008

## Abstract Photo‐oxidation of cyanide was studied in aqueous solution using a low‐pressure ultra‐violet (UV) lamp along with H~2~O~2~ as an oxidant. It was observed that by UV alone, cyanide degradation was slow but when H~2~O~2~ was used with UV, the degradation rate became faster and complete de

The degradation pathway for the oxidation of EDTA in the UV/H 2 O 2 -process was investigated. In absence of iron ions, the mineralization of EDTA is dominated by the reaction of the HO-radicals generated by the photolysis of H 2 O 2 . The organic degradation products iminodiacetate (IMDA), glycinat
