2-Chlorophenol (2-CP) is used as germicida/disinfectant and as precursor for pesticidas and other chlorophenols. It can also be produced as a byproduct in water disinfection and in pulp bleaching.  In the present work the beneficial effect of UVA radiation was studied for the degradation of 2-CP employing the Heterogeneous photo-Fenton reaction using goethite as catalyst. The Fenton reaction has been known for many years and provides a useful tool for pollutant degradation. A subsequent step was the inclusion of UVA radiation to improve yields and facilitate the process economics with the possibility of using solar radiation.
