“…These ions act as electron donors and oxidize to Fe 3+ due to the decomposition of hydrogen peroxide. In Equations 1 and 2 the mechanism of the oxidation reaction through the Fenton process is demonstrated (Giannakis, 2019;Zhu et al, 2019).…”

Organic contaminants in industrial effluents threaten the quality of water resources, especially due to their resistance to natural degradation. The textile industry gain relevance, considering that it generates large volumes. This work aimed to evaluate the efficiency of different advanced oxidation processes (AOP) for the degradation of the mixture textile dyes in solution. After optimization of the main parameters involved in the applied processes and systems, the AOP with greater efficiency in the degradation of the compounds was the photo-Fenton/UV-C (92%) after 360 min of treatment. The experimental data showed a better fit to the Chan and Chu kinetic model and trough an evaluation using artificial neural networks it was possible to predict the maximum degradation achievable by the dye mixture. The toxicity assays, using multiple species of seeds indicated a treated solution with no toxic effects and that the applied methodology can be used without affecting the water resources.

The improper treatment of wastewater has cost humanity a large amount of access to clean water. Treating wastewater, by definition, means to remove pollutants, either physically or chemically. A chemical method of treating wastewater, the Fenton process, was deemed useful for the job. It includes a solution-based reaction that produces radicals to oxidize and break pollutants down. Variations of the Fenton process, each with their unique method, have been developed to increase the process’s efficacy and efficiency further. Admittedly, however, the information on this subject is relatively few, when compared to other more recent methods of treatment. This paper aims to present and discuss a wide variety of information on the Fenton process and its derivatives, including Electro-Fenton, Sono-Fenton, and Photo-Fenton among others.

“…Although a small fraction of pollutants is present in aquatic environments, most of them bio-accumulate and resist traditional physical removal methods [1]. Consequently, innovative strategies, such as advanced oxidation processes (AOPs), have been introduced; the Fenton reaction, which was discovered in 1894, is one of the most studied strategies [2][3][4][5][6][7][8][9][10]. The main reactions stated below [Eqs.…”

“…The main reactions stated below [Eqs. (1), (2)] reveal the major oxidation mechanism, where ferrous ions (Fe 2+ ) continuously react with hydrogen peroxide (H 2 O 2 ) to produce hydroxyl radicals (•OH) with strong oxidizing ability, which plays a vital role in the subsequent degradation of pollutants. The concurrent reduction of ferric ions (Fe 3+ ) to Fe 2+ realizes the circulation of iron ions.…”

Water pollution is a global environmental issue with multi-dimensional influences on human life. Some strategies, such as photo-Fenton reaction, have been employed to remove recalcitrant pollutants. Two-dimensional (2D) graphene and its three-dimensional (3D) configurations have attracted considerable attention as emerging carbon-based catalysts in photo-Fenton fields owing to their alluring properties in electron transfer, reactant adsorption, and light response. This review summarizes the recent developments in 2D and 3D graphene-based catalysts for photo-Fenton reactions. Their structures, characteristics, activity, and mechanisms are discussed. The conclusions and outlooks are proposed for the profound understanding of challenges and future directions.
