Caffeine-modified Magnetic Activated Carbon as Novel Bio Adsorbent for Removal of the Diazinon Pesticide in Aqueous Media

Year: 2024

Type: article

Abstract: Introduction: In this study, a novel composite was prepared using a combination of nanotechnology and biotechnology. Methods: This composite involved loading Fe3O4 NPs and immobilizing caffeine on the surface of activated carbon (CAF-MAC NCs), which was prepared from palm kernel source material. The adsorbent properties were characterized using FTIR, TEM, VSM, and TGA techniques. Results: The adsorbent CAF-MAC NCs were investigated under ultrasound-assisted conditions for the removal of the pesticide diazinon from aqueous solutions. The Langmuir adsorption isotherm model indicated that the maximum adsorption of diazinon was 147.05 mg g-1. Conclusion: The new bio-adsorbent offers several significant advantages, including high adsorption capacity, cost-effectiveness, green synthesis, recyclability, and easy separation.
