- W2358343472 abstract "Surface sediment samples taken from the East China Sea off Changjiang estuary were used as raw materials for phosphorus releasing experiment in mimic marine environment. It is found that after being thoroughly mixed with sea-water for about 10 minutes, phosphorus released from sediment reaches its summit. Adsorption kinetics could be both fitted to the Elovich equation and two-constant rate equation. The releasing amount is closely related to the composition of the sediment. Those consisted mainly of silty and muddy component are higher in phosphorus releasing than those dominated by sandy composition. In the desorption reaction, Fe-P is the most active one, with a releasing ratio higher than other types of phosphorus, followed by Ad-P and O-P. All of them can be refered as bio-acquirable phosphorus. The experiment results demonstrate that phosphorus in sediments can be released into sea-water in suitable hydro-dynamic conditions, and make great impact on nutrition state and primary productivity of marine biosphere." @default.
