Highly regenerative and efficient adsorption of phosphate by restructuring natural palygorskite clay via alkaline activation and co-calcination

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.

Here, a new approach using natural palygorskite structures to create a highly regenerative phosphate adsorbent is proposed. The regeneration via alkaline activation and synthesis via co-calcination restructuring the palygorskite and creating adsorptive metal oxides, leading to excellent regeneration performance and high removal capacity of the phosphate adsorbent.
