Strontium (90Sr) is a typical radionuclide, which can act as contaminant and poses big problem for the eco-environment if left untreated. In this study, an original nitrogen-doped calcite (N-CaCO3) was synthesized using solvothermal calcination method used to remove Sr(II) from simulated water. XRD, SEM, XPS analyses proved that N successfully doped into CaCO3, resulting in porous CaCO3 with regular morphology. The specific surface area of N-CaCO3 (136.53 m2/g) reach 2.19-fold greater than CaCO3. results based on batch adsorption data indicated pseudo-second-order kinetic model (R2 = 0.9964) ion exchange 0.9859) fitted well. as-synthesized exhibited better performance regard low concentrations (below 64.5 mg/L) compared commercial structural analysis suggested Ca played pivotal roles process mechanism dominated by complexation. This study fabricated cleanup, presenting efficient strategy modulate microstructure or other materials, enhance its performance.
