摘要: Abstract Electrokinetic remediation is effective for extraction of contaminants, such as heavy metals, from fine grained deposits. However, several challenges have led to limited field implementation in the US over past two decades. The reasons include lower risk exposure adsorbed contaminants through groundwater, cost treatment, technical difficult soil, and complex geochemical conditions, need acidification induce desorption. To address practical implementation, a Reactive Transference Factor can be used identify conditions that are favorable electrokinetic remediation. factor measures reactive transport rates relative electrical conductivity soil. Other opportunities identified electric-based methods beyond metal extraction. These enhancement bioremediation, which hot spots or source areas, development electrochemical barri...
