%X The sandstone in Chao Lake shore,which rich in iron,aluminum,manganese and other elements,was used to study the adsorption of phosphorus in water.Results show that there is both physisorption and chemisorption in the adsorption process,and chemisorption is dominant.The adsorption process accords with the quasi secondary dynamic model.The adsorption effect is related with initial phosphorus concentration,and the critical concentration point of phosphorus release and adsorption is about 0.04 mg/L.The phosphorus adsorption generated by sandstone accords with Langmuir isotherm equation,and the maximum absorption capacity is about 1 428.57 mg/kg.The peculiar sandstone is better than ordinary sandstone in phosphorus adsorption,which is economically available.
