Efficiency of volcanic ash-based porous geopolymers for the removal of Pb2+, Cd2+ and Hg2+ from aqueous solution

The simultaneous removal of Pb2+, Cd2+ and Hg2+ from an aqueous solution using porous geopolymers from volcanic-ash GP8RHA (incorporating 24.2% of rice husk ash) and GP0 (without rice husk ash) serving as the reference, was performed. In batch experiments, the effects of pH, contact time, adsorbent...
