Adsorption-desorption reactions of phosphorus by lake sediments were studied using radioisotope 32P inorganic phosphate. Exchange rates and amounts of exchangeable P in sediments were measured in aerobic sediments-water batch systems under different pH and phosphorus concentration conditions. Exchangeable P ranged from 6% to 43% of the total P in the sediment without P addition. Increasing pH induced phosphorus desorption from sediments. The relation between the concentration in water and amount of exchangeable P could be explaind by the Langmuir equilibrium model. However, the Langmuir rate equation cannot describe the kinetics of whole exchange reactions. Adsorption-desorption reaction was composed of an exchange reaction and slow reaction. Exchange reaction has two phases-very rapid reaction and a Langmuir type reaction.
