Magnetic carbon-based composites have attracted tremendous research interest owing to their exceptional properties, such as huge surface area, extensive delocalized p-electron system, strong magnetic responsiveness, and excellent mechanical/thermal stability. Magnetic adsorbents can be separated from the solution under an external magnetic field without traditional centrifugation or filtration, eliminating the filtration process. This study showed the importance of hydroxyl groups on carbon when compositing with Fe<sub>3</sub>O<sub>4</sub> based on FT-IR. Besides, a series of magnetic carbon-based composites were synthesized by introducing different concentrations of the iron source to hydroxyl functionalized carbons. They were tested for ibuprofen (100ppm) adsorption, and the best performing magnetic composite showed 28% in absorbing ibuprofen.
