“…It is well known that the molecular weight of dyes changes dramatically depending on the kind of dye being considered. According to the research in this field, dye with a higher molecular weight demonstrated greater removal capability (Keyikoglu & Can, 2021). Higher molecular weight dyes showed improved degradation (%), as seen in Figure 3.…”

A notable level of apprehension exists over the adverse impacts of dye pollution on aquatic ecosystems and human well‐being. The primary objective of this research is to assess the effectiveness of Fenton catalytic reactions in degrading 14 different commercial azo dyes (both single and double) present in aqueous solutions. The investigation focused on the function of dye structures, using a combination of experimental data and examination of theoretical factors. Dye degradation process was carried out at pH 3, and the concentrations of Fe2+ (10−4 mol/L), H2O2 (2 × 10−3 mol/L), and dye (0.05 g/L). The findings revealed that dyes with a larger molecular weight were more effective at degrading (D%), with the overall degradation efficiency varying from 0% to 94%. Functional groups played an important role in degradation efficiency; for example, dyes with higher aromatic rings led to less D%, while a higher number of sulfonic, methyl, and nitro groups was responsible for better D%. Notably, the presence of OH groups in the backbone of dyes (AB 24, ABE 113, and MB 9) formed the Fe complex during the catalytic process, and the D% was minimal. On the other hand, theoretical quantum calculations such as the greater the JCLogP, highest occupied molecular orbital, and Dipole moment value, the higher the degradation efficiency. And dyes with low lowest unoccupied molecular orbital tended to have a better degradation efficiency. To some extent, UV–Vis spectral analysis was investigated to determine the degradation pathway, and the pseudo‐second‐order kinetic model fitted better in the degradation process. The overall experimental and theoretical findings suggested that dye degradation efficiency by the Fenton process is structure‐dependent.Practitioner Points Insights into the role of azo dye structures‐properties on degradation efficiency. Higher molecular weight and sulfonic groups containing dyes showed better degradation efficiency. Hydroxyl groups play the formation of the Fe complex during the degradation process. Higher values of HOMO and lower values of LUMO enhanced degradation efficiency. The pseudo‐second‐order (PSO) kinetic model obeyed the Fenton process.

“…In addition to being a huge water consumer, the textile industry also produces effluents containing hazardous compounds such as dyes. The EC process found application in removing several dyes, such as Reactive Blue 198, Reactive Yellow 145, Reactive Blue 19, Congo Red, and Acid Blue 25 [93][94][95].…”

Effluent treatment and reuse are essential in order to address the global problem of water scarcity. Additionally, improving the quality of treated wastewater is necessary to reduce its adverse effects on natural water resources and, consequently, on human health. Electrocoagulation and adsorption have been successfully applied separately to treat different wastewaters. Each method has unique benefits, drawbacks, and parameters that affect the effectiveness of treatment. A review of both processes, including their theoretical principles, the effect of operating conditions, and practical applications, is presented to provide an overview of their capabilities. The combination of electrocoagulation and adsorption in a combined process can be used to amplify the advantages of each process while mitigating their limitations. In the present work, the combined process is analyzed in terms of its principles, applications, and integration in a circular economy model.

“…18 The observation of MG residues in fish tissue suggests the potential entry of this toxic chemical into the food chain and endangers human health. 19 To date, a variety of approaches namely ion exchange membrane separation, 20 Bioremediation, 21,22 photochemical degradation, electrocoagulation, 23 adsorption, and fenton-biological degradation 24,25 have been developed to treat dye-laden wastewater. The adsorption approach is widely favored owing to its cost-effectiveness, ease of implementation, outstanding effectiveness, and ability to facilitate sludge-free cleaning operations.…”
