Superior comprehensive performance of modified activated carbon as a hexavalent chromium adsorbent.

The presence of hexavalent chromium species (Cr) in wastewater from manufacturing industries such as electroplating and leather production can pose serious health hazards. To address these concerns, this study developed a novel adsorbent based on activated carbon as the primary material to attract Cr. Activated carbon has been modified with several other components to improve its comprehensive performance, including adsorption capacity, chemical stability, collectability, and reusability.
