Introduction:

Industrial activities generate polluted wastewaters with a vast variety of contaminants that may form a mixture of compounds in a wide range of concentrations. The growth of wastewater production has become a major problem to be solved due to the presence of persistent organic pollutants that cannot be conveniently removed through conventional treatments. The toxicity associated to these harmful pollutants constitutes a serious environmental health problem that requires the development of more effective technologies for the removal of such toxic organic pollutants from wastewaters.

Oxidation technologies that could be conducted at atmospheric pressure and mild temperatures represent desirable alternatives from an economical point of view. Advanced oxidation processes (AOPs), such as ozonation, photocatalysis , electrochemical processesand Fenton’s Reagent, or using catalytic wet peroxide oxidation (CWPO). The use of advanced oxidation aims to eliminate these pollutants or at least reduce the hazardous nature of treated aqueous waste to allow a subsequent conventional treatment.
