This paper focus on the adsorption of phosphorus onto blast furnace slags. Its equilibrium isotherm and kinetic model were investigated by using different models. The Langmuir, Freundlich and Temkin isotherms were applied to describe the experimental isotherm data and the results showed that the Langmuir isotherm was the best to characterize the phosphorus adsorption behavior on the blast furnace slags with the maximum adsorption capacity of 1341.6mg/kg. The kinetics studies at different initial phosphorus concentrations showed that greatest amount of phosphorus adsorption were completed during the first 10h. Although the process of phosphorus adsorption as a function of time can be suitably described by first-order and pseudo second-order kinetics, the pseudo second-order kinetics are proved to be the best with the similar qe with the experimental data.
