Sediment Phosphorus Mechanism in Aquatic Ecosystems

Sediment phosphorus sorption is the key mechanism used in the sediment-water phosphorus dynamic and mobility in aquatic environments. This mechanism comprises a process for sediment phosphorus adsorption and desorption. Estimation of sediment phosphorus ratio longevity has priority in the determination of sediment pollution and lake management applications. Some developed equations are generally used in the sediment phosphorus adsorption and desorption mechanism. Freundlich ve Langmiur isotherms, based on experimental study, are frequently used. Equilibrium phosphate concentration (EPC0) defined as the equilibrium between adsorption and desorption in aquatic systems is commonly used to assess the potential for sediment to uptake or release phosphate prior to the reduction in external phosphate source. This study examines the estimation of some equations used in the sediment phosphorus sorption and the effective physico-chemical parameters
