Selective Adsorption of Sr(II) from Aqueous Solution by Na3FePO4CO3: Experimental and DFT Studies
Journal: Molecules
Year: 2024

The efficient segregation of radioactive nuclides from low-level radioactive liquid waste (LLRW) is paramount for nuclear emergency protocols and waste minimization. Here, we synthesized Na<sub>3</sub>FePO<sub>4</sub>CO<sub>3</sub> (NFPC) via a one-pot hydrothermal method and applied it for the first time to the selective separation of Sr<sup>2+</sup> from simulated LLRW. Static adsorption experimental results indicated that the distribution coefficient <i>K<sub>d</sub></i> remained above 5000 m
