Characteristics of Phosphorus Sorption-Desorption Kinetics by the Colloidal Dispersion Complex in Black Soil

Abstract:

The black soil was taken as the research object, and the phosphorus sorption-desorption kinetics characteristics of different components of colloidal dispersion complex in black soil were studied. Results showed that the maximum phosphorus adsorption amount by different components of the colloidal dispersion complex decreased in the order of G₀< G₁2, and the adsorption amount would be stable as the time increase, while the desorption amount was in the order of G₁>G₀>G₂. The Elovich equation was the optimal model to describe phosphorus adsorption by different components of colloidal dispersion complex, which fitted better than the Two-constant equation.
