摘要

本研究报道了单宁酸和三价铁修饰的Fe3O4纳米颗粒的制备和应用，用于去除铀（Ⅵ）。单宁酸分子上的酚羟基可与铀(Ⅵ)络合，从而达到吸附废水中铀的目的，TA-FeⅢ@Fe3O4的最大吸附量可达98.2 mg/g。通过对吸附剂的 pH 值、用量、吸附动力学和吸附热力学的研究表明，该吸附剂是除去废水中铀（Ⅵ）的一种新型绿色吸附剂。

Tannic acid and trivalent iron modified Fe3O4 nanoparticles as a new adsorbent to remove uranium from wastewater

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-Fe^III@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.
