Metal-free high-adsorption-capacity adsorbent derived from spent coffee grounds for methylene blue
Heavy-metal-free carbon materials were prepared from spent coffee grounds (SCG) using the coupled KOH–urea and NaOH–urea as activating agents, and these were compared with SCG activation by the alkali salts alone. SCG was impregnated with the activating agents before being pyrolyzed at 800 °C under...
