Comparative Analysis and Kinetic Modeling of Marbofloxacin Degradation via Electro-Fenton and Biodegradation Optimization

Abstract

In the quest for sustainable water purification methods, electrochemical Advanced Oxidation Processes (AOPs) emerge as pivotal strategies against organic pollutants. This study delves into the efficacy of the Electro-Fenton process, a distinguished AOP that leverages the in-situ generation of hydroxyl radicals (•OH) via the electrochemical reduction of oxygen. By conducting systematic experiments in deionized water, we evaluate the influence of catalyst concentration, applied current density, and cathode material selection on the degradation kinetics of marbofloxacin – a model pharmaceutical pollutant. Employing advanced statistical and kinetic modeling, our investigation reveals critical insights into the process dynamics, uncovering the nuanced interplay between operational parameters and degradation efficiency. The findings substantiate the Electro-Fenton process as an environmentally advantageous and effective solution for water decontamination and advancing the field of water purification technology.
