Fenton reaction has proven to be an interesting working area among the Advanced Oxidation Technologies. The process is usually fast and can have thermal and photochemical improvements with solar applicability. In the last years, it has been suggested to use immobilized iron containing compounds in many different forms to overcome the iron separation problem. This technology, known as Heterogeneous Fenton, uses hydrogen peroxide (H2O2) and a solid iron carrier As expected, it shares some advantages with the classical Fenton process: (i) it can be significantly improved with temperature and (ii) it can be combined with UVvis radiation (the Heterogeneous Photo-Fenton reaction) which implies the possibility of using solar illumination when using goethite as catalyst.In the present work the influence of irradiation was studied for the degradation of the model compound 2-Chlorophenol (2-CP). Goethite was used as a source of iron. The influence of catalyst loading and initial molar ratio between hydrogen peroxide and contaminant (R) was also examined.
