在这项研究中，对从土耳其科尼亚Seydisehir获得的废赤泥(铝土矿残渣)样品在氨水溶液中合成纳米Fe3O4(NPs)进行了评估，该纳米颗粒可用于从合成和天然地下水样品中去除As(V)。用透射电子显微镜、振动显微镜、X射线衍射仪、小角X射线衍射仪、热重分析和红外光谱对所合成的纳米Fe3O4进行了表征。Fe3O4纳米粒子呈近球形，平均尺寸为9 nm。结果表明，以废赤泥为原料合成的Fe3O4-NP5具有良好的磁性能和对As(V)的吸附能力，特别是在低平衡砷酸盐浓度下。(C)2012 Elsevier B.V.保留所有权利，
In this study waste red mud (bauxite residue) sample obtained from Seydisehir (Konya, Turkey) was evaluated for the synthesis of Fe3O4 nanoparticles (NPs) in ammonia solution that can be used to remove As(V) from both synthetic and natural underground water samples. The synthesized Fe3O4-NPs were characterized by using TEM, VSM, XRD, SAXS,TGA and FT-IR spectroscopy. The Fe3O4-NPs assumed a near-sphere shape with an average size of 9 nm. The results showed that synthesized Fe3O4-NP5 from waste red mud have satisfactory magnetic properties and As(V) sorption capacity, especially at low equilibrium arsenate concentrations.
