“…A technique known as soil washing uses two processes to remove pollutants from soil: physical separation and chemical leaching by aqueous solutions. This method starts with a homogenization step in which the coarse particles are divided based on their densities [35]. Depending on the type of metal and soil, the contaminated soil is dug up and combined with an appropriate extractant solution during soil washing [36].…”

The food security of human societies has become a major source of worry due to heavy metal contamination in soils and water supplies. Water and soil sources are becoming more and more contaminated with heavy metals every day as a result of the development of several mining techniques and technologies as well as the expansion of numerous enterprises. A career assessment predicts a 7–10% increase in employment for soil and plant scientists between 2018 and 2028. Because the production of wholesome food and the safety of food are very important issues. Therefore, some of the innovative techniques for eliminating organic and mineral contamination from water and soil sources are addressed in this book chapter.

“…Electrokinetic remediation has recently emerged as a method that effectively removes metals, anions, and polar organics from contaminated soils [ 29 ]. The compounds that have been studied using electrokinetic remediation in previous work include total petroleum hydrocarbons, trichloroethane, chlorophenols, toluene, polychlorinated biphenyls, phenols, BTEX compounds (such as ethylbenzene, benzene, toluene, and xylene), volatile organic compounds, lead, mercury, uranium, zinc, nickel, copper, chromium, cadmium, and arsenic [ 22 , 25 , 28 , 30 ].…”

“…In electrolysis, chemical reactions occur at the electrodes to decompose water into ions and gases [ 23 ]. Electroosmosis involves movement of pore liquids in the media due to the existence of the electrical double layer at the solid–water interface [ 23 , 24 , 29 ]; electrophoresis involves movement of charged colloids in the medium relative to the stationary fluid of the media [ 23 ], while diffusion is the distribution of compounds in the media from regions of higher concentrations to regions of lower concentrations [ 25 ]. Electromigration, on the other hand, is regarded as the main mechanism for electro-remediation and involves movement of charged ions to oppositely charged electrodes due to application of an electric field [ 23 , 29 ].…”

Acar et al [ 28 ] argues that electrokinetic remediation is considered a technically feasible and cost-effective method of decontamination of contaminated soil because of the complementary combination of electrolysis, electroosmosis, electrophoresis, diffusion, and electromigration.…”

Electrokinetic remediation has, in recent years, shown great potential in remediating polluted environments. The technology can efficiently remove heavy metals, chlorophenols, polychlorinated biphenyls, phenols, trichloroethane, benzene, toluene, ethylbenzene, and xylene (BTEX) compounds and entire petroleum hydrocarbons. Electrokinetic remediation makes use of electrolysis, electroosmosis, electrophoresis, diffusion, and electromigration as the five fundamental processes in achieving decontamination of polluted environments. These five processes depend on pH swings, voltage, electrodes, and electrolytes used in the electrochemical system. To apply this technology at the field scale, it is necessary to pursue the design of effective processes with low environmental impact to meet global sustainability standards. It is, therefore, imperative to understand the roles of the fundamental processes and their interactions in achieving effective and sustainable electrokinetic remediation in order to identify cleaner alternative solutions. This paper presents an overview of different processes involved in electrokinetic remediation with a focus on the effect of pH, electrodes, surfactants, and electrolytes that are applied in the remediation of contaminated soil and how these can be combined with cleaner technologies or alternative additives to achieve sustainable electrokinetic remediation. The electrokinetic phenomenon is described, followed by an evaluation of the impact of pH, surfactants, voltage, electrodes, and electrolytes in achieving effective and sustainable remediation.

“…Soil washing involves mixing the soil with a solvent and separating out soils based on particle size distribution. Significant contaminant mass is usually adsorbed to clay and silt deposits, which can be separated from the sand and gravels (Fernández Rodríguez et al, 2014), with some contaminants removed to wash water during this process . Different solvents or techniques such as ultrasound are used to enhance PFAS desorption, discussed in more detail in sections 3.3 and 4.2, respectively.…”
