In this study, a novel magnetic material was applied as an adsorbent for simultaneous removal of Pb(II) and Cd(II) ions from aqueous solutions. The adsorbent was synthesized using functionalized MnFe₂O₄ magnetic nanoparticles grafted to lamellar graphene oxide surface (MnFe₂O₄@SiO₂‐NH₂@GO) and characterized using X‐ray diffraction, Fourier transform infrared spectroscopy, scanning electron microscopy, thermogravimetric analysis and magnetic measurements.

基于氧化石墨烯的可回收磁性复合材料的制备，用于快速去除水溶液中的铅和镉离子

在这项研究中，一种新型磁性材料被用作吸附剂，用于从水溶液中同时去除Pb（II）和Cd（II）离子。吸附剂是使用功能化的MnFe ₂ O ₄磁性纳米颗粒接枝到层状氧化石墨烯表面（MnFe ₂ O ₄ @SiO ₂ -NH ₂ @GO）合成的，并使用X射线衍射，傅里叶变换红外光谱，扫描电子显微镜，热重分析和磁测量。
