Abstract Purpose The study focuses on the use of surfactants as enhancing solutions in electrokinetic remediation trials sediments, with hypothesis that they will allow heavy metals to desorb from organic matter, and thus favour their removal solution. Materials methods A total 15 were conducted. As solutions, four different non-ionic commercial used, either alone or combination citric acid (CA...

Electrokinetic techniques have attracted considerable attention due to their competitive advantage in enhancing transport phenomena and remediation of low permeability soils. However, many types low-permeability porous media, such as active clays like bentonite, present a double porosity structure that strongly affects mass transfer processes. In this work, we develop modeling approach simulate...

Thousands of sites are contaminated with both heavy metals and organic compounds and these sites pose a major threat to the environment. Very few technologies, such as soil washing=flushing and stabilization=solidification, are available to remediate these sites; however, all these technologies are ineffective under low permeability and heterogeneous soil conditions. Previous studies have shown...
