  Abstract:  It was studied the photooxidation with hydrogen peroxide of some waters containing the organic dye – Brown Vopsider DNRL 101 – in different conditions of operation. It was proposed a mathematical model of the studied process having two independent variables: pH and irradiation time. Also, there were determined the best operational conditions and the optimum value of the decolouring degree. The dye destruction was appreciated through the removal of samples colour expressed through the decolouring degree.
