Metal Foam-Based Fenton-Like Process by Aeration |

2020-1-12A novel metal foam-based Fenton-like process for wastewater treatment is illustrated in this study. In the system, H2O2 was generated in situ by taking advantage of O2 in air, as metal could activate dissolved O2 to produce O2 and then generate H2O2. Furthermore, metal foam can enhance the Fe3Fe2 cycling, which eventually improved the efficiency of the Fenton process. The
