Metal Foam-Based Fenton-Like Process by Aeration.

ABSTRACT: A 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 Fe³⁺/Fe²⁺ cycling, which eventually improved the efficiency of the Fenton process. The performance of the novel Fenton-like process was assessed by methyl blue (MB), and 94% MB removal could be achieved within 5 min in nickel (Ni) foam system. The degradation of MB in this study was based on both ^•OH and ^•O₂^- radicals, where ^•O
