In this study, macadamia nutshell residue, a prevalent leftover and green agricultural waste in Vietnam, was utilized to prepare magnetic activated carbon adsorbent. The obtained material characterized by its surface functionalities, elemental composition, crystalline structure, properties. characterization results revealed that the composite comprised Fe3O4 nanoparticles attached matrix. satur...

Graphene oxide (GO) was synthesized using Sri Lankan naturally available graphite and Fe3O4 nanoparticles were successfully incorporated fabricating magnetically separable GO/Fe3O4 nanocomposite. The nanocomposites characterized by X-ray diffractometry (XRD), Scanning electron microscopy (SEM), FT-IR spectroscopy. Crystalline phases of GO identified XRD patterns, while the presence functional g...
