This study addresses high fluoride levels (>1.5 mg/L) in drinking water using volcanic rock materials in column systems. Characterization techniques informed adsorption mechanisms. VPum removed110 mg/kg, VSco 22 mg/kg. Zirconium-coated adsorbents, Zr – Pu (225 mg/kg) and ZrOCSc (58 mg/kg), enhance fluoride adsorption. Models predicted upscaling without the need for more experiments. Volcanic rocks, natural or modified, can efficiently remove fluoride in fixed-bed adsorption columns. Research on competing ions and adsorbent regeneration is crucial for sustainable groundwater defluoridation.<eng>
