“…Prior to the past two decades or so, BEs were largely referred to as fluidized bed electrodes and were used for designing industrial reactors meant for applications in processes such as electrosynthesis, and water splitting, and also for the purposes of increasing fuel cell performances [ 36 ]. Before being widely adopted for electroanalytical purposes, BPE had attracted great attention and had been used for many years in a variety of fields including battery technologies [ 37 ] concentration enrichment [ 38 ], separation [ 39 ] wastewater treatment [ 40 ], etc. In their research, Laws and others also investigated BPEs as a means of enriching and separating charged species electrokinetically where a single Au BPE was used to locally enrich several different charged markers in a single microchannel [ 39 ].…”

Recently, there has been an upsurge in the extent to which electrochemiluminescence (ECL) working in synergy with bipolar electrochemistry (BPE) is being applied in simple biosensing devices, especially in a clinical setup. The key objective of this particular write-up is to present a consolidated review of ECL-BPE, providing a three-dimensional perspective incorporating its strengths, weaknesses, limitations, and potential applications as a biosensing technique. The review encapsulates critical insights into the latest and novel developments in the field of ECL-BPE, including innovative electrode designs and newly developed, novel luminophores and co-reactants employed in ECL-BPE systems, along with challenges, such as optimization of the interelectrode distance, electrode miniaturization and electrode surface modification for enhancing sensitivity and selectivity. Moreover, this consolidated review will provide an overview of the latest, novel applications and advances made in this field with a bias toward multiplex biosensing based on the past five years of research. The studies reviewed herein, indicate that the technology is rapidly advancing at an outstanding purse and has an immense potential to revolutionize the general field of biosensing. This perspective aims to stimulate innovative ideas and inspire researchers alike to incorporate some elements of ECL-BPE into their studies, thereby steering this field into previously unexplored domains that may lead to unexpected, interesting discoveries. For instance, the application of ECL-BPE in other challenging and complex sample matrices such as hair for bioanalytical purposes is currently an unexplored area. Of great significance, a substantial fraction of the content in this review article is based on content from research articles published between the years 2018 and 2023.

“…The experimental results showed that the removal efficiencies of total solids, COD, total nitrogen, and total phosphorus were 30%, 81%, 37%, and 99.9%, respectively. Qi et al [14] reported an integrated electrocoagulation process that was based on horizontal bipolar electrodes and investigated the pollutant removal efficiency and energy consumption in different configurations of a two-dimensional electrocoagulation system. The above-mentioned literature studies indicate that many scholars have systematically studied the electrocoagulation mechanism, potential applications, and technical improvements.…”

At present, methods for treating tertiary oil recovery wastewater via electro-coagulation are still in their early stage of development. In this study, a device for electro-coagulation wastewater treatment was built and tested in an oil field. The effects that the initial pH value, electrode type, and connection mode have on the coagulation and separation effect were assessed by measuring the mass fraction and turbidity of oil. The results have shown that when the electro-coagulation method is used, the effectiveness of the treatment can be significantly increased in neutral pH conditions (pH = 7), in acidic conditions, and in alkaline conditions. Compared to an Al electrode, the floc that is produced by an Fe electrode is smaller; thus, it does not easily coagulate and settle in a short time. Using the oil removal rate, turbidity removal rate and energy consumption as a basis to assess the performances, the results have demonstrated that the combined aluminum alloy iron composite electrode should be used as electrolytic electrode.

“…Electrocoagulation (EC) is a water and wastewater treatment process that uses electrochemical, chemical, and physical mechanisms to electrochemically dissolve cationic metallic ions in situ by oxidizing a sacrificial anode using just electric current and the dissolved electrodes produce a coagulant species that destabilizes and traps pollutants in the form of suspended particles in water and wastewater, forcing them to form flocs and precipitate, resulting in the removal of pollutants ( Ebba et al., 2021 ). The electrocoagulation process was a system when only electric current was applied to the required wastewater under treatment with other appurtenances, and to increase the motion of suspended and colloidal pollutants that resulted in producing sensitive coagulants from the reaction of electrode reactions ( Esfandyari et al., 2019 ; Garcia-Segura et al., 2017 ; Qi et al., 2020 ). Recent researchers suggested that electrocoagulation is the most important technology implemented for water and wastewater treatment due to its environmental friendly ( Koyuncu and Arıman, 2020 ; Nugroho et al., 2019 ), the high removal efficiency of pollutants ( Koyuncu and Arıman, 2020 ; Nugroho et al., 2019 ), high energy efficiency ( Nagarajappa and Impa, 2015 ), cost-effectiveness ( Nagarajappa and Impa, 2015 ), avoiding the usage of chemicals ( Koyuncu and Arıman, 2020 ) and a small amount of sludge produced compared to chemical treatment methods ( Papadopoulos et al., 2019 ).…”

Electrocoagulation is an electrochemical method that uses sacrificial electrodes to remediate wastewater. The combination of electrodes for the treatment of domestic wastewater is the factor that influences the removal efficiency of COD (Chemical Oxygen Demand) by using the electrocoagulation process. Aluminum and Iron electrodes are combined as anode-cathode and cathode-anode in Al–Al, Fe–Fe, Al–Fe, and Fe–Al. Different factors are considered to evaluate the removal efficiency of COD like; pH (3–9), reaction time (15–60 min), and current density (9.23–45 A/m 2 ). Based on this influencing factor Al–Al and Fe–Fe can remove COD up to 87.5 % and 90 % respectively. Similarly, 87.5 % and 88.89 % of COD were removed, when aluminum and iron were combined as Al–Fe and Fe–Al respectively. In addition, the effects of different operating parameters were discussed on the removal percentage of COD. This indicated that the combination of electrode influence the removal efficiency of COD using the electrocoagulation process under different operating parameters.
