“…Increasing environmental awareness and the fact that countries have targets for environmental sustainability necessitate the efficient and environmentally friendly treatment of industrial wastewater. Electro-Fenton process, which is one of the advanced oxidation methods meeting these criteria, can be used to effectively remove toxic and/or persistent organic pollutants (Basturk et al, 2021;Dolatabadi & Ahmadzadeh, 2019;Liu et al, 2023;Shoorangiz et al, 2019), dyes Iranpour et al, 2018) and phenols (Al-Zubaidi & Pak, 2020) from water.…”

Waste water containing reactive textile dyes constitutes an important environmental problem as they are permanent and dangerous. The Electro-Fenton (EF) method is promising as an effective technique for the degradation of organic materials such as dyestuffs. In this study, the optimization of effective variables in the removal of reactive yellow 145 azo textile dye by the EF using response surface methodology (RSM) was investigated. Central composite design (CCD) was used to study the combined effects of key parameters such as voltage (2.5–12.5 V), H2O2 addition (0.1–1.3 mL), pH (1.75–4.75), electrode spacing (0.25–3.25 cm), and treatment time (25–85 min). The optimum values of the variables to ensure the highest dye removal efficiency (approx. 93%) with the lowest energy consumption (approx. 3.4 Wh/L) are approximately 9.4 V voltage, pH 3.7, 2.5 cm electrode range, 1 mL H2O2 addition, and a 40-minute treatment time. ANOVA analysis of the predicted quadratic polynomial model showed a regression coefficient value of approximately 0.97 for both objective functions; this highlights the applicability of the model for navigating the design space. Simultaneous optimization of process parameters using RSM was achieved with a low number of experiments.

“…Designed using electrochemical principles, these processes are of great interest due to their ability to ensure environmental compatibility (Ismail et al, 2021). The electro-Fenton process, which has gained attention in recent years, is an economical and environmentally friendly process that can be used to efficiently remove toxic and/or persistent organic pollutants such as pharmaceuticals (Basturk et al, 2021, Dolatabadi and Ahmadzadeh, 2019, Liu et al, 2023, Shoorangiz et al, 2019, dyes (Cruz-González et al, 2012, Iranpour et al, 2018 and phenols (Al-Zubaidi andPak, 2020, Rahmani et al, 2015) from water.…”

Electro-Fenton (EF) is a system where electrooxidation and electrocoagulation come together. In the EF method, it is aimed at creating OH radicals in an electrochemical cell by catalyzing H2O2 with Fe2+ ions. In this study, optimization of process variables for the removal of reactive azo dye (reactive yellow 145) from aqueous solution by the electro-Fenton method was carried out using response surface methodology. The percentage of dye removal and energy consumption were selected as the response functions for the 5 variables determined as voltage, H2O2 concentration, pH, electrode spacing, and processing time. As a result of 32 experiments determined by the Design Expert 13 program, the effect of variables on response functions was examined separately and together. 10 V voltage to 99.4%, which is the highest removal; pH 2.5; 1 cm electrode range; 1 mL H2O2 addition; and 22.16 Wh/L energy consumption in a 70-min treatment time were reached. The optimum values of the variables proposed by the program to ensure the highest dye removal efficiency (approximately 93%) and the lowest energy consumption (approx. 3.4 Wh/L) are approximately 9.4 V voltage, pH 3.7, 2.5 cm electrode range, 1 mL H2O2 addition, and a 40-minute treatment time.
