Highly efficient cu2+ adsorption using oxygen-plasma-modified activated carbon derived from coffee grounds
Activated carbon derived from agricultural biomass has emerged as a promising adsorbent for heavy metal removal due to its low cost, environmental sustainability, and tunable surface properties. In this study, activated carbon was synthesized from waste coffee grounds via anaerobic pyrolysis at different temperatures (...
