Permeable Reactive Barrier of Coated Sand by Iron Oxide for Treatment of Groundwater Contaminated with Cadmium and Copper Ions

In this research, coated sand iron-oxide (CSIO) has been used as a permeable reactive barrier (PRB) for removal of cadmium and copper ions from the contaminated groundwater. The prepared material has been manufactured by precipitation of nano-particles based this oxide type on the sand surface...
