One-step synthesis of magnetic composite UiO-66/Fe3O4/GO for the removal of radioactive cesium ions

In this study, the UiO-66/Fe3O4/GO composite was prepared by one step method for removal of cesium ions (Cs+) in water and exhibited excellent adsorption capacity for Cs+ (62.07mgg(-1)), which can be attributed to the size compatibility of nanosized cavities and the addition of GO. As supporting matrix, GO decreased particle aggregation and increased the surface area of the adsorbent. The composite had good acid and alkali resistance, thermal stability, rapid adsorption rate and can be separated from water by magnetic separation rapidly.
