Activated carbon from olive pomace for hexavalent chromium removal: synthesis, characterization, and adsorption mechanism analysis.

ABSTRACT: Chromium contamination, particularly in industrial wastewater, poses significant environmental and health risks due to its toxicity, carcinogenicity, and persistence. Despite various treatment methods, developing cost-effective and sustainable adsorbents remains challenging. This study addresses this gap by investigating the potential of activated carbon derived from olive pomace for Cr(VI) removal from aqueous solutions. The activated carbon was synthesized via chemical activation with phosphoric acid (H₂PO₄) followed by calcination at 500 °C. The structural and chemical properties of the adsorbent were characterized using FT-IR, HRTEM, SEM, XRD, and Raman spectroscopy. Additionally, density functional theory (DFT) calculations were employed to optimize the activated
