The potential of activated palygorskite was assessed for sorption of phosphate from aqueous solution. The natural palygorskite used was treated by thermal activation over 100–1000 °C for 2 h. The thermal activation increased the phosphate sorption capacity and the highest phosphate sorption capacity...
