Phosphate Adsorption and Desorption in Aged Refuse

Yujiang Yang

Abstract

The characteristics of phosphate adsorption and desorption were investigated in different paddy soils and aged refuses under constant temperature. The results indicated that all phosphate adsorption curves could be described by Langmuir,Freundlich and Temkin equations. Compared with paddy soils, the maximum phosphate adsorption of aged refuse increased significantly and the desorption rate was approximate to paddy soils. The main factors affecting phophate absorption and desorption were pH?humus?active ferric oxide?active aluminous oxide?CaCO3 and CEC.
