Electrokinetic Remediation for Environmental Security and Sustainability Explore this comprehensive reference on the remediation of contaminated substrates, filled with cutting-edge research and practical case studies Electrokinetic Remediation for Environmental Security and Sustainability delivers a thorough review of electrokinetic remediation (EKR) for the treatment of inorganic and organic contaminants in contaminated substrates. The book highlights recent progress and developments in EKR in the areas of resource recovery, the removal of pollutants, and environmental remediation. It also discusses the use of EKR in conjunction with nanotechnology and phytoremediation. Throughout the book, case studies are presented that involve the field implementation of EKR technologies. The book also includes discussions of enhanced electrokinetic remediation of dredged co-contaminated sediments, solar-powered bioelectrokinetics for the mitigation of contaminated agricultural soil, advanced electro-fenton for remediation of organics, electrokinetic remediation for PPCPs in contaminated substrates, and the electrokinetic remediation of agrochemicals such as organochlorine compounds. Other topics include: A thorough introduction to the modelling of electrokinetic remediation An exploration of the electrokinetic recovery of tungsten and removal of arsenic from mining secondary resources An analysis of pharmaceutically active compounds in wastewater treatment plants with a discussion of electrochemical advanced oxidation as an on-site treatment A review of rare earth elements, including general concepts and recovery techniques, like electrodialytic extraction A treatment of hydrocarbon-contaminated soil in cold climate conditions Perfect for environmental engineers and scientists, geologists, chemical engineers, biochemical engineers, and scientists working with green technology, Electrokinetic Remediation for Environmental Security and Sustainability will also earn a place in the libraries of academic and industry researchers, engineers, regulators, and policy makers with an interest in the remediation of contaminated natural resources.

This paper investigates the feasibility of electrokinetic remediation of contaminated sediment at Indiana Harbor, Indiana. The sediment is a fine-grained material with high moisture content of 78 % and high organic content of 19 % and it is contaminated with a wide range of polycyclic aromatic hydrocarbons (PAHs) and heavy metals. Four bench-scale electrokinetic experiments were conducted at 2.0 VDC/cm of constant voltage gradient using two surfactants (5 % Igepal CA-720 and 3 % Tween 80), a cosolvent (20 % n-butylamine), and a cyclodextrin (10 % HP-?-CD) as flushing solutions for the solubilization/desorption of PAHs. The mobility and removal of heavy metals was also investigated while flushing these solutions. The experimental results show that 20 % n-butylamine and 5 % Igepal 720 systems are effective for the partial solubilization of the PAHs in the sediments; however, both 3 % Tween 80 and 10 % HP-?-CD systems are found to be ineffective for desorption/solubilization of PAHs in the sediment. None of the selected flushing agents is found to be effective for the removal of heavy metals from the contaminated sediment. The low removal of PAHs and heavy metals is attributed to the high organic content and high acid buffering capacity of the sediment.

An evaluation of the efficiency of rhamnolipids (biosurfactants) used in electrokinetic remediation of soil contaminated with phenanthrene was presented. Bench scale tests were conducted using four experimental series in order to determine the feasibility and mechanisms of biosurfactant-enhanced phenanthrene removal from mica soil. The bench-scale study showed that bacteria (Pseudomonas aeruginosa) could survive to a certain extent when a low voltage DC electric field was applied. In addition, it was found that these bacteria could produce rhamnolipids in the clayey soil under the electric field. Experimental results showed that during the 14-day experimental period, phenanthrene was partially removed. The highest removal was achieved in the cathode area (85% removal). These promising results are an indication that this process can be applied as an in-situ enhancement technique for improving the efficiency of electrokinetic soil remediation. It was proved that bio-micelles, formed due to the introduction of ex-situ produced biosurfactants, could be transported to the electrode areas due to both electroosmotic and electrophoretic phenomena. It also indicated that the electrokinetic introduction of engineering produced biosurfactants into the contaminated clayey soil was feasible. The mechanisms involved in the formation of bio-micelles, were described in a bench-scale test using Fourier Transform Infrared Spectrometers (FTIR) and Atomic Force Microscopy (AFM). Results permitted to describe that the transformation of bio-micelles kinetically changed under the electric field. It was found that spherical, bilayer, and multi-lamellar micelles were formed at different phases of the electrokinetic experiment. The presence of clayey particles and the electric field attenuated and deferred the formation of bio-micelles. Knowledge of the kinetics of bio-micelle formation process are paramount to the accurate application of biosurfactants in electrokinetic remediation of PAH contaminated clayey soil. The effort to desorb and solubilize phenanthrene, by promoting the formation of bilayer bio-micelles, became successful in bench-scale electrokinetic experiments. In addition, the successful ex-situ production of biosurfactants can be used on an industrial scale for electrokinetic soil remediation. The above-described developments can be applied as a new in-situ remediation technology: bio-electrokinetics.
