Abstract：

　　　　　　　　　90Sr　is　one　of　the　highly　radioactive　and　hazardous　nuclides　in　nuclear　waste　liquids.　The　high　water　solubility　and　mobility　of　90Sr2+　ions　make　it　difficult　to　effectively　remove　90Sr　from　the　complex　aqueous　environment.　Herein,　K2SbPO6,　a　phosphatoantimonate　ion　exchange　material　with　an　excellent　removal　ability　for　Sr2+　ions,　has　been　organically　granulated　with　polyacrylonitrile　(PAN)　by　an　automated　method　to　form　K2SbPO6/PAN　composite　microspheres.　The　K2SbPO6/PAN　microspheres　with　radiation　resistance　exhibit　a　high　maximum　adsorption　capacity　(qmSr)　of　131.15　mg　g−1　for　Sr2+　ions　and　retain　the　high　removal　rate　(RSr)　in　a　wide　pH　range　(pH　=　3–12).　It　is　important　that　K2SbPO6/PAN　microspheres　could　efficiently　treat　Sr2+　ions　solutions　in　a　dynamic　adsorption　manner　even　at　970　bed　volumes　(RSr　＞　81%).　This　work　paves　the　way　for　the　preparation　of　low-cost　ion　exchange　materials　with　the　advantages　of　regular　shape　and　easy　operation　by　a　simple　and　fast　method　and　the　practical　application　of　powdered　ion　exchange　materials.　©　2024　by　the　authors.
