    Abstract:

    In this paper,Langmuir isotherm was used for the interpretation of the phosphate adsorption in soils.The soil samples tested were collected from the representative soils in north-eastern China.Meanwhile,the fractionation of inorganic phosphates were conducted.Results showed that the maximum adsorption was conrrelated negatively with soil pH,and positively with CEC.Moreover,the product of parameters in Langmuir equations (K1×K2 was conrrelated negatively with desorption %:Besides,the acid soils were rich in occluded Fe-P,but low in desorption %.While the calcareous soils generally possessed higher desorption %,even though the Ca-P and Fe-P in soils were extremely high.The Al-P was increased after the soil samples treated with KH2PO4solution.The Al-P was increaced with the increase of phosphate adsorption.
