     in this work, the degradation of chlorimuron-ethyl, which belongs to the class of sulfonylurea herbicide, was performed by fenton, photo-fenton and ozonation. at the used experimental conditions, photo-fenton degradation was influenced by the initial h2o2 and fe2+ concentration. in the case of its degradation by ozonation, the best results were achieved when ozone was combined with uv and h2o2. among the studied aops, photo-fenton presented the best result concerning mineralization and chlorimuron-ethyl degradation, achieving degradations higher than 85% after 90 min of reaction. based on the obtained results, the photo-fenton system can be an important technique to be applied in the treatment of wastewater containing this pesticide.
