Resumen:
The application of heterogeneous Fenton-like systems was studied, using an industrial paper mill effluent and a model solution of sodium acetate. The reaction was investigated in both a batch and a fixed bed reactor, at 70 °C, over CuO/γAl2O3 spheres, calcined at 900 °C. For the batch experiments performed with the industrial effluent, the TOC conversions were close to 45%, with leaching levels below 0.1 ppm Cu. In the continuous system, TOC reductions of the effluent were near 20% after 4 h ofoperation. The discoloration degrees and oxidant consumptions were complete and the estimated reductions in aromatics content were between 60-70% (SUVA 254 nm). The impact of two reaction parameters (oxidant concentration and residence time) was investigated, with a slightly positive effect.
