Abstract
Herein, we present a new strategy to create a highly regenerative and efficient phosphate adsorbent based on activating natural palygorskite structures. Both the regeneration via alkaline activation and synthesis via co-calcination restructured the palygorskite and created adsorptive metal oxides. The phosphate adsorbent exhibits excellent regeneration performance with high removal capacity.
