Arsenic contamination of water has become a crucial water quality problem in many parts of the world considering the fact that the source of pollution is mostly contaminated soils. To overcome this problem many new technologies are being developed, among them using nanoparticles as a new class of adsorbents is becoming attractive because of their high specific surface area and higher surface reactivity due to their extremely small size. In this research, iron/copper bimetallic nanoparticles were used to remove arsenic from aqueous solutions as well as to stabilize arsenic in an industrial contaminated soil. Results of this study show that Fe/Cu nanoparticles are effective for removing arsenic from aqueous solutions and have the potential for developing a simple process for field applications to stabilize arsenic in soil.
