Removal of dyes from aqueous solutions by adsorbent prepared from coffee residues

This study reports the production of an adsorbent material derived from extracted coffee residues using phosphoric acid and zinc chloride as activating agents. The structural features of the materials were characterized using different analytical techniques. The BET surface areas were found between...
