Phosphate adsorption capabilities of different activated attapulgites were investigated. The natural attapulgites were treated by thermal activation over 120-800 °C for 2 h, and by hydrochloric acid solution from 1%-9%, respectively. The mechanisms of phosphate adsorption of these modified products...
