A hydroxyl-functionalized magnetic fungus nanocomposite (MFH@GO) was prepared by a simple one-pot method for the removal of Cr(VI) from wastewater. The adsorption behavior of MFH@GO to Cr(VI) in wastewater was discussed in detail. At pH of 5.0 and temperature of 323.15 K, MFH@GO had higher adsorption capacity to Cr(VI) (58.4 mg/g) than the unmodified fungus and GO. Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), thermogravimetry and differential thermal analysis (TG-DTA), scanning electron microscopy and energy dispersive X-Ray spectroscopy (SEM-EDX) were employed to d...

本文采用一种简单、温和的方法制备了富含功能基团的磁性菌丝复合材料MFH@GO,并用于处理废水中的Cr(VI)。详细地研究了MFH@GO对Cr(VI)的吸附性能。结果表明,在pH值为5.0,温度为323.15 K的条件下,MFH@GO对Cr(VI)的最大吸附量达到58.4 mg/g,远高于未改性的菌丝粉和氧化石墨烯。通过FTIR,XRD,TG-DTA,SEM和EDX等分析MFH@GO的特性及对Cr(VI)的吸附机理,结果表明,铁及氧化石墨烯纳米颗粒显著改善了菌丝的理化特性,MFH@GO能够将Cr(VI)还原成无毒的铬酸铁化合物存在于残留物中。该研究结果表明MFH@GO在处理Cr(VI)废水中具有较大的潜力和应用价值。
