“…The core findings of this study proved the non-toxic nature of the remediated wastewater produced when EFT was employed. In contrast, Divyapriya et al (2018) investigated the performance of EFT using a ferrocenefunctionalized graphene oxide-based electrode for ciprofloxacin removal under the effect of applied voltage (-0.75 --2.5 V) and solution pH (3)(4)(5)(6)(7)(8)(9). The highest removal efficiency of 99% was obtained at pH 7 and 2 hours of contact time.…”

“…They found that there was no notable increase in pollutants elimination after the 5 th -cycle of electrode reusability at any conditions of solution pH. He et al (2018) used a (g-C 3 N 4 /ACF) electrode in an electro-Fenton reactor to remove TOC from wastewater under the influence of the reaction time of (0-240 min), current density of (1-4 mA/cm 2 ), and solution pH (2)(3)(4)(5)(6)(7). They attained 91% of TOC removal after 4 hours, 3 mA/cm 2 , and pH 3.…”

“…A three-dimensional iron foam was conducted by Zheng et al (2019) as an electrode in an electro-Fenton reactor to eliminate COD and total nitrogen under the effect of the operating conditions of the initial COD concentration (5000-15000 ppm), applied current (100-400 mA), contact time (0-350 min), and solution pH (3)(4)(5)(6)(7)(8)(9). Within 6 h of electrolysis, they obtained 44% and 70% reduction in COD and total nitrogen content, respectively, using at solution pH 3 and 300 mA of applied current.…”

“…Baiju et al (2018) integrated EFT with a biological method to enhance the biodegradability of leachate attaining COD removal efficiency of 97% after 90 min of the reaction time, 5 V of applied voltage, and solution pH 2. As well, Gholizadeh et al (2020) investigated the performance of integrating EFT with the biological system to remove contaminants from wastewater under the effect of initial concentration of phenazopyridine drug (5-30 ppm), applied current (0.1-0.4 A), plant amount (5-25 g), treatment time (0-48 h), and solution pH (5)(6)(7)(8)(9)(10)(11). They found that 99% of drug removal could be obtained within 120 min at pH 7 and 0.2 A of applied current using 20 g of plant amount.…”

Several conventional methods have been employed to eliminate numerous types of pollutants from domestic and industrial wastewater. Electrochemical techniques are one of these treatment methods used in wastewater treatment. Electro-Fenton technology (EFT) is one type of electrochemical technique. The present review paper aims to provide readers with extensive information about the EFT general definitions, terminologies, mechanisms, fundamental conditions, and statistical analysis based on the published articles for the recent years. The core findings of this work proved that the EFT is more applicable for removing organic contaminants than inorganic ones because of the affinity degree between the adsorbents formed in the reactor and the pollutants. The most important conditions of this technology are the type of anode, the applied current, and the period of the treatment process. The development of the conventional cathode electrode was the most interested field in the literature. The advantages of EFT provide the ability to perform it as a primary or secondary treatment process with other conventional treatment processes. The statistical analysis shows that 68% of the selected cited articles achieved a high performance of EFT when it has performed alone while 32% of these cited articles attained the best performance of EFT in the integrated system with other technologies. The electro-Fenton method is a promising technology to treat wastewater, especially that involving organic pollutants

“…Similarly, processes involving metals such as the electroplating industry generate metal-rich wastewater [ 8 , 9 , 10 ]. The concentration of components creates an environmental pollution crisis, which affects fauna and flora due to the increase in chemical oxygen demand (COD) [ 11 ]. Therefore, wastewater must undergo treatment using available technologies before being discharged into water bodies or soil.…”

Electrochemical wastewater treatment technologies are gaining attraction as sustainable alternatives for industrial and municipal wastewater management. This study conducts a comprehensive life cycle assessment to assess the environmental and economic sustainability of electrochemical methods such as electrocoagulation, electrooxidation, and electroreduction. By analyzing key stages, from raw material extraction to end‐of‐life disposal, the review aims to provide insight into their overall sustainability performance. The study also delves into environmental impact categories and utilization of methods used in quantifying the environmental implications. Moreover, a cost structure analysis and cost‐effectiveness evaluation offer insights into the economic viability of these technologies. Despite facing challenges like high initial costs and regulatory constraints, electrochemical technologies demonstrate competitive advantages in treatment efficiency and energy savings. Collaborative efforts and supportive policy frameworks are deemed crucial for overcoming barriers and fostering the widespread adoption of electrochemical technologies, thereby advancing sustainable wastewater management practices.
