“…For example, electrochemical remediation has been well advanced towards the remediation of PFASs [20,21]. The increasing attention can be evidenced in Figure 1whilst Table 1lists the typical PFASs discussed in this review.…”

“…However, even for the water sample, EAOP usually needs a pre-treatment or extraction module to address issues of efficiency and anode shelf life, as discussed above. This pre-treatment module might also be used for soil remediation [21]. In this process the PFASs will be extracted from the contaminated soils and transformed to the water media [72].…”

“…Note, there are several options in terms of electrochemical remediation [31], such as electrocoagulation [73], electrokinetics [21], electrodeposition [29] and geooxidation [74,75], etc. Among these, the geooxidation process showed promise in breaking down some POPs from soil.…”

Abstract:Per-and polyfluoroalkyl substances (PFASs) have been recently listed as emerging contaminants (ECs) and persistent organic pollutants (POPs) due to their human and environmental health concerns. In the last 10 years, their detection and remediation have progressed significantly. Herein, we critically review recent developments in electrochemical advanced oxidation process (EAOP) towards their remediation. Particular attentions are paid to perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), which present the main concerns of PFASs at this time. Due to the persistence of those PFASs, other remediation approaches may experience difficulty in degrading them, whilst EAOP has demonstrated success. The fundamentals of EAOP are highlighted and the scale-up application is discussed regarding the future research directions.

“…This study scale is often referred to as a microcosm study and focuses on the electro-biodegradation of contaminants such as pesticides [9] [175], and petroleum spills [12] [158] [172], and are also used to easily study and optimize some operational electrochemical parameters such as polarization curves, coulombic efficiency and activation, ohmic and transport losses.…”

“…The microbiological processes, involved in bio-electrochemical remediation of recalcitrant pollutants, are currently not fully understood, particularly in relation to electron transfer mechanisms. Some reviews provide a comprehensive analysis of the research on bio-electrochemical remediation and of the key parameters involved in the process [9] [12] [172]. As show in Table 1 [177] [178], and even inorganic species [179].…”

This review describes a new means of control and stimulation of microorganisms involved in the bioremediation of sediments and waterlogged soils. This emerging technology is derived from sedimentary microbial fuel cells, and consists in ensuring aerobic respiration of aerobic microbial populations in anaerobic conditions by means of a fixed potential anode in order to evacuate the electrons coming from the microbial respiratory chains. This review describes the conceptual basis of the electro-bioremediation, the material devices used (electrode set-ups and spacing), and finally studies the various devices published since the bench tests until the scarce in-field implementations.

Significant concerns continue to be raised over environmental pollution of soils and water resources. Chemical fate and transport coupled with redox manipulation are the primary processes that have been considered for removing contamination and minimizing exposure. Electrochemical processes utilize electron transfer to drive transport of chemicals and redox manipulation for treatment of contaminated media. Electrokinetic remediation relies on the electric field to transport contaminants in low permeability soils toward the electrode vicinity for removal. In water cleanup, both electroreduction and electrooxidation have been used. Electroreduction has been used for dechlorination and defluorination of halogenated calcitrant compounds. Electrooxidation has also gained significant potential for transformation of many legacy and emerging contaminants. For example, organic contaminants could be oxidized directly on anode surface (direct anodic oxidation), by electrochemically generated hydroxyl radicals or by other electrochemically generated oxidants (indirect anodic oxidation). In this article, we present an overview of the state‐of‐the‐art electrochemical processes for treatment of contaminated soil and water. We also describe a perspective for future research directions in the field of electrochemical treatment of contaminated media.
