摘要：

This study reports the preparation and application of Fe3O4 nanoparticles modified by tannic acid and trivalent iron for U(Ⅵ) removal. The phenolic hydroxyl group on the tannic acid molecule can be complexed with U(Ⅵ), so as to achieve the goal of adsorping uranium from wastewater, and the maximum adsorption capacity of TA-FeIII@Fe3O4 can reach 98.2 mg/g. Through the research on pH, dosage, adsorption kinetics and adsorption thermodynamics indicted that it were excepting as a new green adsorbent for removing U(Ⅵ) from wastewater. This study ...
