Glyphosate is an organophosphate herbicide, which is the one most used in the world. The disposal of pesticide wastewaters including equipment rinsates and unusable product such as empty plastic pesticide containers remains an unsolved problem in many countries. In this work the potential of the h2o2/uv process for treating the wastewater from rinsing commercial containers of glyphosate was studied. The wastewater was degraded in a photoreactor and the experiments were carried out under several experimental conditions. The obtained results were compared with the experiments made using glyphosate alone (as active ingredient, in abscence of other compounds existing in commercial formulations).
