Radioactive cesium ^ 137 C ^ + is one of the most dangerous radionuclides that exists in radioactive wastewater. Fast, low-cost, efficient and environmentally friendly adsorbents are in need to remove ^ 137 C ^ + from the affected waters in order to protect the environment from the adverse effects of ^ 137 C+. Based on two well-known remedial adsorbents namely, nanoscale zerovalent iron (NZVI) and zeolite, nine nanoparticle and nanocomposites were synthesized and tested toward the removal of cesium from contaminated waters. The performance of nanoparticles (NZVI, Cu/Fe, Ni/Fe and Ag/Fe) was disappointing because their removal efficiencies could not exceed 10%. On the other hand, zeolite and its magnetic nanocomposites Ze/Fe, Ze/Fe-Cu, Ze/Fe-Ni and Ze/Fe-Ag were effectively able to recover the cesium from contaminated water by 99.92%, 61.25%, 53.95%, 37.68% and 53.92%, respectively.
