Fe3O4/Fe2O3-MIL-101 synthesized using carboxylated Fe3O4/Fe2O3, chromium nitrate nonahydrate, terephthalic acid under microwave irradiation. A new composite, i.e. Fe3O4/Fe2O3-MIL-101-NH2 was also synthesized under microwave irradiation condition. The composites were characterized with the help of XRD, FT-IR, SEM, EDX, TEM, DSC/TGA and VSM. XRD analysis depicts preservation of iron oxide and MIL-101 peaks in the composite, i.e. Fe3O4/Fe2O3-MIL-101. The transformation of Fe3O4/Fe2O3-MIL-101 to Fe3O4/Fe2O3-MIL-101-NH2 occurred with a decline in the organic content of the product. The EDX analysis depicted the presence of both chromium and iron in both composites. Ferromagnetic nature of both the composites ascertained with the VSM analysis. The Fe3O4/Fe2O3-MIL-101 depicted low adsorption capacity for both cadmium (2.79 mg/g or 41.17 % removal at initial cadmium concentration of 6.8 mg/l) and nickel (1.29 mg/g or 16.88 % removal at initial nickel concentration of 7.7 mg/l). The Fe3O4/Fe2O3-MIL-101 did not show any zone of inhibition with different bacteria during the ecotoxicity study.

微波溶剂热处理氧化铁/MIL-101复合材料的合成与表征

Fe 3 O 4 /Fe 2 O 3 -MIL-101使用羧化Fe 3 O 4 /Fe 2 O 3、九水合硝酸铬、对苯二甲酸在微波辐射下合成。在微波辐射条件下还合成了一种新型复合材料,即Fe 3 O 4 /Fe 2 O 3 -MIL-101-NH 2。借助 XRD、FT-IR、SEM、EDX、TEM、DSC/TGA 和 VSM 对复合材料进行表征。XRD 分析描述了复合物中氧化铁和 MIL-101 峰的保留,即 Fe 3 O 4 /Fe 2O 3 -MIL-101。Fe 3 O 4 /Fe 2 O 3 -MIL-101 向 Fe 3 O 4 /Fe 2 O 3 -MIL-101-NH 2 的转变伴随产物有机物含量的下降而发生。EDX 分析描述了两种复合材料中都存在铬和铁。通过 VSM 分析确定了两种复合材料的铁磁性质。Fe 3 O 4 /Fe 2 O 3-MIL-101 描述了镉(2.79 mg/g 或 6.8 mg/l 初始镉浓度时去除率为 41.17%)和镍(1.29 mg/g 或初始镍浓度 7.7 mg/l 时去除率 16.88%)的低吸附容量)。在生态毒性研究期间,Fe 3 O 4 /Fe 2 O 3 -MIL-101 对不同细菌没有显示任何抑菌圈。
