Synthesis of magnetic FeO/graphene aerogel for the removal of 2,4-dichlorophenoxyacetic acid herbicide from water.

Graphene-based aerogels are among the lightest materials in the world and have been extensively studied for environmental remediation. In this work, an FeO/graphene aerogel material was synthesized using the co-precipitation method. The prepared material was characterized using X-ray diffraction (XRD), scanning electron microscopy/X-ray energy dispersive spectroscopy (FESEM/EDX), infrared spectroscopy (FT-IR), and vibration sample magnetization (VSM).
