Summary: The recovery of uranium from strong acid media is a challenge due to the poor structural stability and low uranium adsorption performance of magnetic nanomaterials. In this study, a core-shell magnetic nanocomposite Fe3O4@SiO2/P (MBA-VPA) was fabricated to address these issues. The sorbent exhibited a record-breaking maximum adsorption capacity of 262.5 mg g-1 and excellent selectivity for uranium in the presence of multi-ions. Additionally, the sorbent showed excellent acidic resistance and could be magnetically recovered and reused multiple times.

Summary: In this paper, phosphate-modified biochar supporting nano zero-valent iron (PBC/nZVI) was successfully prepared and fully characterized. The introduction of polyphosphate greatly increased the specific surface area of biochar pores, and then zero-valent iron was evenly distributed on the material surface, leading to excellent removal performance of PBC/nZVI for U(VI). This work proves that PBC/nZVI has a wide application prospect in the field of uranium wastewater treatment.
