“…Few organic intermediates were detected at the very beginning of the electrolysis but total depletion was then observed . During the treatment of polycyclic aromatic hydrocarbons and TW80‐containing SW solution, a slight accumulation of short‐chain carboxylic acids was detected during the first hours of the treatment but the process was also able to achieve the mineralization of these compounds at longer treatment times . However, a different trend was reported by Saez et al.…”

“…One of the major drawbacks of AO is still the energy consumption because of high charges required to reach full mineralization and detoxification of the solution. For example, 15 Ah L −1 , corresponding to 127 kWh m −3 , was required for achieving 70 % COD removal from a SW solution containing an initial organic load of 2,700 mg L −1 of COD . However the combination of AO with a more cost‐effective biological treatment can reduce global operating costs .…”

“…However the combination of AO with a more cost‐effective biological treatment can reduce global operating costs . In fact, 80 % COD removal was achieved by performing AO at only 1.9 Ah L −1 in combination with a post‐biological treatment . As regards to operating conditions, high current density might not be the most suitable choice in view of a combination with a post‐biological treatment because of the complete mineralization of organic compounds without accumulation of (biodegradable) by‐products .…”

“…These results might be attributed to the ability of BDD anode to avoid the accumulation of toxic degradation by‐products. For the treatment of SW solutions with moderate biodegradability, the most suitable treatment strategy might be to use AO as a post‐treatment following a biological treatment in order to remove initially the biodegradable fraction of the organic load and then, to focus AO on the low biodegradable fraction …”

The chemical stability and electrocatalytic properties of boron‐doped diamond (BDD) electrodes give rise to various applications. While wastewater treatment is the most widely studied field, the use of BDD for soil remediation and environmental sensing is currently investigated more and more. With regards to soil remediation, promising results have been reported for the treatment of soil washing solutions. Anodic oxidation using BDD at high current density allows high mineralization rates of biorefractory soil pollutants and extracting agents to be reached. At low current density, selective degradation of target pollutants has been achieved, thus allowing the reuse of extracting agents for further soil washing steps. BDD‐based electrochemical sensors have been studied for chemical oxygen demand determination, pesticide/pharmaceutical detection as well as other applications such as pH, O2 and analysis of various organic and inorganic compounds. Low detection limits, wide linear ranges and low standard deviations have been achieved. The main reasons behind the superiority of BDD sensors are the chemical stability, wide applicability and resistance of BDD towards biofouling. The beauty of BDD sensing is that it can work for a variety of organic and inorganic compounds under many physicochemical parameters.

“…Therefore, it was demonstrated that AOPs/EAOPs can enhance the biodegradability of recalcitrant effluents, measured by the ration BDO 5 /COD . More recently Oturan's group demonstrated that electro‐Fenton process can be utilized as pre‐treatment stage before a biological treatment ,. These studies have shown that the coupling between electro‐Fenton and biological degradation is a reliable strategy for removal of POPs from water in an efficient and cost‐effective way.…”

Over the past few decades, environmental applications of the boron‐doped diamond (BDD) electrode are reported to be vast and versatile. Applications of BDD electrodes in the field of electrochemical advanced oxidation processes (EAOPs) for the abatement of toxic persistent organic pollutants are significant, owing to the easy and effective way of treatment. This article focuses on highlighting and summarizing the applications of the BDD electrode for the treatment of different synthetic and real wastewaters, such as those involved in pharmaceuticals and personal care products, pesticides/herbicides, dyes, etc. We also review the processes and methodologies involving the synthesis of BDD electrodes and summarize the desirable characteristic features required for the application of EAOPs. Applications of BDD electrodes for the treatment of wastewater through different EAOPs, including anodic oxidation, electro‐Fenton, coupling processes such as electro‐Fenton pyrite, bioelectro‐Fenton, and their recent advancements are also discussed in detail. It envisages the greater potential for complete treatment of different toxic wastewater effluents. This Review shows that the application of BDD electrodes in the field of wastewater treatment is tremendous and proves to be a promising material for future perspectives.

Soil remediation by electro-Fenton (EF) process has been recently proposed in literature. Being applied for solutions treatment, EF is mainly combined with soil washing (SW)/soil flushing (SF) separation techniques to remove the organic pollutants. The main criteria influencing the combined process have been identified as: (i) operating parameters (electrode materials, current density and catalyst (Fe 2+ ) concentration), (ii) the matrix composition (nature and dose of extracting agent, pH, complexity of SW/SF solutions), and (iii) the environmental impact (acute ecotoxicity and biodegradability of effluent as well as impact on soil microbial activity). The influence of these parameters on the SW/EF and SF/EF integrated processes has been reviewed. Energy consumption calculations have been finally considered as it constitutes the main source of operating cost in EF process.
