Degradation of Methylorange by Fenton Reagent

Abstract

Synthetic dyes play a significant role in various industries, including textiles, paper, food, leather, cosmetics, and pharmaceuticals, with azo dyes being the predominant category. However, their widespread use has led to a pressing environmental issue due to the release of these dyes into wastewater, posing concerns for public health. To address this problem, numerous advanced oxidation processes (AOPs) have been devised, among which Fenton oxidation has gained prominence for its ability to break down these dyes. This review compiles the most recent research findings on the photo-Fenton and electro-Fenton degradation of methylorange (MO).
