Lake eutrophication is one of the most important environmental problems in our country, furthermore, the studies on phosphorus action in the interface of sediment-water is one of the key elements which helps find the mechanism of eutrophication. Among these, the studies on phosphorus forms and phosphorus adsorption of sediment are crucial aspects that can further reveal the mechanism of phosphorus action in the interface of sediment-water and supply direction and theoretical grounds to treatment and managem...
