摘要

Iron phosphate materials (FeP-A(B)) were synthesized via a one-pot strategy, with their compositions tailored by adjusting the phosphate acid content and the Fe3+/Fe2+ ratio. Among these, FeP-2(1) exhibited the best U(VI) adsorption capacity. Batch experiments revealed a maximum adsorption capacity of 147.4 mg g−1 at pH 4.5, reaching equilibrium within 12 h, surpassing several reported adsorbents. Moreover, FeP-2(1) showed excellent selectivity and maintained high removal efficiency over five consecutive cycles, indicating strong reusability. Mechanistic analysis confirmed that U(VI) uptake occurs mainly through complexation with surface phosphate groups. These findings highlight FeP-2(1) as a promising adsorbent for U(VI) remediation in aqueous systems.
