Recently, Journal of Materials Chemistry A (doi: 10.1039/C3TA13548A.) published online the academic paper of the Department of Environmental Restoration and Material Technology of the Northeast Institute of Geography and Agroecology, Chinese Academy of Sciences. In situ Controllable Synthesis of Magnetic Prussian Blue/Graphene Oxide Nanocomposites for Removal In Radioactive Cesium in Water, the article reported on "selectively and efficiently purifying radioactive cesium in nuclear waste water using magnetic Prussian blue/graphene oxide nano-adsorbents." Nuclear radiation pollution caused by nuclear leakage is the biggest hidden safety and environmental protection problem in nuclear energy applications. Studies have shown that the nuclear pollution components include cesium (Cs-131, 133, 137), thorium (Sr90) and iodine (I-131, 135) and other radioactive elements, including radioactive cesium (12.8%, half-life of about 30 years). One of the main ingredients. Aiming at the reality of the lack of nuclear pollution purification materials and technologies in the world today, researchers from the Northeast Institute of Geography and other researchers at the Northeast Institute of Chemistry have conducted a pioneering and successful study to prepare “magnetic Prussian blue/graphene oxide†nanomaterials for high-efficiency radioactive cesium absorption at 50 ppm. The rapid removal rate of the thorium in the sewage can reach more than 90%; the saturated adsorption capacity of the lanthanum ion can reach 55.56mg/g. At the same time, the adsorbent can quickly and easily separate from the nuclear waste water under the action of an external magnetic field. What is more important is that the material has good radiation stability and selective adsorption of cesium ions. Even in the sea water with complex composition, the material has almost no effect on the purification and magnetic recovery of helium. The research results will have a positive impact on the progress of nuclear pollution purification materials and technologies in China and even the world.
