This Research Topic focuses on presenting cutting-edge techniques to investigate and mitigate/remediate emerging contaminants, including microplastics, pharmaceuticals, and PFAS, as well as persistent contaminants such as petroleum hydrocarbons and heavy metals. There are different techniques and approaches that have been used in mitigation, remediation, and treatment of contaminated surface water, groundwater and soils. For instance, the reduction of surface tension using surfactants, sorbents, biochar and polymers to remove contamination, and the mobilization of contaminants via electrochemical transport mechanisms, including electroosmotic flow and electromigration.
The collection presents an opportunity for the researchers to promote the use of energy-efficient, innovative techniques to mitigate surface water, groundwater, and soil contamination. The use of radicals to oxidize contaminants is a promising technique. For instance, hydroxyl radicals produced from an electrochemical process can be used to remediate and mitigate contamination with organic compounds. Explore new areas of research that help understand the complexity of contamination in surface water, groundwater and soil.
Polymers, such as polypropylene, polyurethane, and various copolymers, are commonly used for sorption of petroleum hydrocarbons. These materials can be tailored to enhance their sorptive capacity and selectivity for specific hydrocarbon compounds. The molecular structure of these polymers can be modified to improve their sorption efficiency, mechanical strength, and reusability, making them versatile tools in environmental protection.
Biochar, a carbon-rich material derived from the pyrolysis of biomass, has gained significant attention for its potential in adsorption due to its high surface area, porous structure, and surface functionality. Utilizing biochar and other sustainable materials for adsorption is an eco-friendly approach to address various environmental issues such as water pollution, soil contamination, and air quality.
Different types of surfactants, including anionic, cationic, non-ionic, and amphoteric surfactants, are used to reduce surface tension. Innovative hybrid techniques to remediate contaminated sites, including bioremediation combined with chemical oxidation, phytoremediation coupled with soil amendments, electrokinetic remediation integrated surfactant flushing, and thermal desorption paired with solidification/stabilization.
This Research Topic aims to explore several themes of interest, encompassing but not limited to:
• Investigation of the production and potential of radicals in mitigating organic compounds
• Exploring the use of ozonation in electrokinetic and electrochemical applications
• Strategies to enhance oxidation of contaminations in-situ and ex-situ applications
• Exploring the application of polymers in mobilizing organic and inorganic compounds in subsurface conditions
• Investigating the use of biochar and sustainable materials in the adsorption of contaminants.
• Exploring the use of electrokinetic remediation to mitigate contaminated soils
• Different applications of electrokinetic, including desalination, soil remediation, wastewater treatment, and reclamation of phosphorus and other chemical compounds
• Discuss the combination of electrokinetics with other techniques. For instance, electrokinetic bioremediation, electrokinetic phytoremediation, … etc.
