Abstract:

A comparative experimental study on methanol, formaldehyde and p-chlorophenol degradation with hydrogen peroxide by advanced oxidation process Photo-Fenton type is presented. The degradation process is determined by the very high oxidative potential (2.8V) of the OH. radicals generated inside the reaction medium by Fe2+/3+ catalyst coupled with UV radiations. The influence of the hydrogen peroxide excess, initial solution's pH, Fe2+/3+ catalyst concentration, nature and initial concentration of organic compounds and reaction time on the oxidation process are presented.

Keywords:

Photo-Fenton process, oxidation, methyl alcohol, formaldehyde, p-chlorophenol.
