Abstract: The recovery of ethylenediaminetetraacetic acid (EDTA) from washing effluents is essential to reduce the cost of EDTA-enhanced soil washing and the production of wastewater. This study evaluated a recovery method, in which ...

Abstract: The effects of the operating conditions, the initial concentrations of heavy metals in soils, and the competition among heavy metals during ethylenediaminetetraacetic acid (EDTA)-enhanced soil washing were extensively ...

Abstract: The application of zero-valent iron

Abstract: Eleven columns were set up under various groundwater geochemistry conditions to investigate the competitive effect of trichloroethylene (TCE) on hexavalent chromium [Cr(VI)] removal by zero-valent iron

Abstract: A funnel-and-gate permeable reactive barrier (PRB) packed with zero-valent iron

Abstract: Centrifuge modeling appears to be a useful experimental tool to study geoenvironmental problems, such as pollutant migration in subsurface systems. In this paper, the migration process of light nonaqueous phase liquids ...

Abstract: The phosphoric acid activated carbon (PAC) was derived from waste wooden pallets by a two-step chemical activation technique, carbonization and phosphoric acid activation in sequence. A widely used commercial activated ...
