Exploring the pressurized heterogeneous electro-Fenton process and modelling the system

In this research, a bench-scale installation was tested for the heterogeneous electro-Fenton treatment of clofibric acid. The setup consists pressurized flow-through electrochemical cell equipped with catalyst fluidized-bed and aerated jet mixer. novelty research is two-fold: use pressurized-jet aerator on an it one first studies combining pressure catalysis in electro-Fenton. Moderate relative pressures, up to 2 bar, were analyzed. Initially, electrogeneration hydrogen peroxide tested, showing that remarkably boosted by application pressure. Then, elimination acid means carried out at 0.12 0.25 A, using iron-containing alginate beads as catalyst. Regardless current intensity, increase from atmospheric 1 gauge bar pollutant reduced specific energy consumption cell. Specifically, A abatement higher than 98% achieved 8 h while only required However, further did not report major improvement. Moreover, effect analyzed, concluding integrity compromised fact, iron leaching very similar 0, bar: around 30% after treatment. Finally, mathematical model developed, experimental data obtain necessary fitting parameters, which allowed understand better behavior reaction system.
