| Sumario: | In this work, we propose a novel approach to dye decomposition under subcritical water conditions using a continuous-flow tubular reactor coated with thin layer of PdO as a catalyst. Remazole Brilliant Blue R was used as an example of synthetic dyes. Hydrogen peroxide was used as an environmental-friendly oxidant as it leaves no residues after treatment. The effect of temperature, pressure and dye concentration on total organic carbon (TOC) removal were studied. 99.9% of TOC removal was achieved at 300 °C and 10 MPa pressure within a short residence time of 3.2 s. This method provided an efficient and rapid process that has a potential for treating a wide range of textile wastewaters. |
