Simultaneous Galvanic Generation of Fe2+ Catalyst and Spontaneous Energy Release in the Galvano-Fenton Technique: A Numerical Investigation of Phenol’s Oxidation and Energy Production and Saving

The present paper investigates the potential of Galvano-Fenton process as an advanced technique in terms simultaneous oxidation a model pollutant, phenol, and energy release saving compared to conventional electrochemical techniques, namely, Fenton, Fenton-like, Electro-Fenton. A numerical describing electrochemical, electrolytic, phenol’s mineralization reactions is presented. Simulations are conducted predict kinetics ferrous ferric ions, radicals’ formation, phenol degradation along with released power. Parametric analysis comparisons also performed between basic configuration its upgraded version integrating pre-immersion stage electrodes electrolyte equivalent 25% total experiment’s duration. ratio initial concentration H2O2 released/added Fe2+ catalyst varied from 10 30. effect inspected over range 0.188 mg/L well. Compared Fenton-based demonstrated higher performance by reaching 1.34% efficiency per J. This associated generation hydroxyl radicals 0.047 nM/released J concentrations hydrogen peroxide 0.187 mM 2 µM, respectively. Moreover, integration allowed overcoming barrier null rate at instant.
