This study aims to prepare in manganese ferrite/graphene oxide (MnFe2O4/GO) nanocomposites for the removal of ibuprofen drug residue from water. The synthesised nanocomposites with various MnFe2O4 content from 30–60 wt.% were characterised by X-ray diffraction, Fourier transform infrared spectroscopy, transmission electron microscopy, vibrating sample magnetometer, Brunauer - Emmett - Teller specific surface area, and energy dispersive X-ray. It was found that the suitable mass ratio of MnFe2O4 in nanocomposite for ibuprofen removal was 50 wt.%. The adsorption process followed the pseudo-second-order kinetic and Langmuir isotherm model. The maximum capacity of MnFe2O4/GO was found to be 156.25 mg g−1. Accordingly, the MnFe2O4/GO could be used as an efficient adsorbent for the removal of ibuprofen from water.

制备磁性锰铁氧体/氧化石墨烯纳米复合材料作为布洛芬的高效吸附剂

本研究旨在制备锰铁氧体/氧化石墨烯 (MnFe 2 O 4 /GO) 纳米复合材料,用于去除水中布洛芬药物残留。通过 X 射线衍射、傅里叶变换红外光谱、透射电子显微镜、振动样品磁强计、Brunauer-Emmett-Teller 比表面积和能量色散对合成的具有30-60 wt.% MnFe 2 O 4含量的纳米复合材料进行表征。 X 射线。发现用于去除布洛芬的纳米复合材料中MnFe 2 O 4的合适质量比为50wt.%。吸附过程遵循伪二级动力学和朗缪尔等温线模型。发现MnFe 2 O 4 /GO的最大容量为156.25 mg g -1。因此,MnFe 2 O 4 /GO 可用作从水中去除布洛芬的有效吸附剂。
