| Abstract: | This research studies the reliability of an activated carbon permeable reactive barrier in removing cadmium from a contaminated shallow aquifer. Laboratory tests have been performed to characterize the equilibrium and kinetic adsorption properties of the activated carbon in cadmium-containing aqueous solutions. A 2D numerical model has been used to describe pollutant transport within a groundwater and the pollutant adsorption on the permeable reactive barrier (PRB). In particular, it has been considered the case of a PAB used to protect a lake or downstream from Cd (Ⅱ) contaminated groundwater. Numerical results show that the PAB can achieve a long-term efficiency by preventing lake or downstream pollution for several months. |
