Strontium (90Sr) is a typical radionuclide. which can act as a contaminant and poses a big problem for the eco-environment if left untreated. In this study. an original nitrogen-doped calcite (N-CaCO3) was synthesized using a solvothermal and calcination method and used to remove Sr(II) from simulated water. https://safeersappliancers.shop/product-category/rangemaster-longstock-90cm-dual-fuel-range-cooker-stainless-steel/
