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 surfaces by impregnation process. Therefore, this technique can be considered the main objective of the present study. The description of sorption data for sorbate-sorbent under consideration by the Langmuir isotherm model was more valuable than the Freundlich model. The maximum adsorption capacity of CSIO reaches 1.9181 and 7.6425 mg/g for cadmium and copper respectively. COMSOL Multiphysics Version release 3.5 has a good ability in the simulation and prediction of the cadmium and copper transport through one-dimensional CSIO-PRB. The outcome of this investigation prove that the manufactured CSIO has significant capability in the delay of contaminants the migration through barrier packed with this material. The root means squared errors between predicted and measured data were not exceeded the 0.121; so, this means that there a good agreement between these data
