The catalytic potential of activated red mud in the degradation of effluents (sour waters) was studied from the improvement process of heavy and extra-heavy crudes treated by advanced oxidation processes using solar radiation. A factorial experiment design 22 with two points to the center was applied. Analytical techniques were used to the effluent to evaluate parameters such as: COD, TPH, Conductivity, pH, concentration of sulphides, concentration of sulfates, chlorides, ICP-MS and IC. For the identification of organic compounds, a solid phase microextraction was applied and then a GC-MS. The solids were analyzed by XRD, FTIR, and carbon / sulfur LECO. The POA allowed obtaining results in the reduction of COD by 88.95% and TPH by 100%, also reducing the sulfur concentration by 99.99%. It was concluded that the reaction is carried out for heterogeneous catalysis and that the carbon absorption in the catalyst is less than 0.2%.
