Adsorption is considered to be an effective and simple method for radioactive nuclides removal from low and intermediate level radioactive wastewater(LILW)in the nuclear industry.Many nanomaterials with excellent performance are always prepared as composites for engineering application.The properties of LILW and latest advances in adsorption progress are analyzed in this paper.The research developments on novel hybrid microbeads suitable for nuclear power applications,such as exo-situ fixation microbeads,polymer microbeads and magnetic microbeads,are especially focused on.The pros and cons of these materials and performance improvement methods are analyzed in terms of raw materials,base materials,preparation methods,and adsorptive properties.Furthermore,according to the nuclear industrial requirements for the LILW treatment,it is pointed that lack of tests with radioactive and engineering tests are the key problems of current studies.Future research directions are proposed aiming at the hope of developing adsorbents removing multiple nuclides,strengthening of numerical simulation and forcusing on more continuous operation inspection.
