Abstract: This paper introduced the commonly used dynamic models of phosphorous adsorption-desorption (Langmuir equation, Freundlich equation, and Temkin model), analyzed their interrelationships, summarized the present researches on the dynamic models of phosphorous adsorption-desorption, and presented the unified expression form of different dynamic models. It was proposed that in the future, more researches would be oriented to the phosphorous adsorption-desorption characteristics of wetland sediments, related dynamic models for different types of wetland, long-term monitoring of the special characteristics of phosphorus adsorption-desorption in wetland sediments, and the interactive effects of different environmental factors, aimed to deepen our understanding on the dynamic models and to fully understand the operation mechanisms of wetland ecosystems from the viewpoint of purification mechanisms.
