Phosphorus Adsorption Desorption Model of River Sediment

摘要

Phosphorus adsorption and desorption in natural waters have played a crucial role in the ecology of rivers and reservoirs. Hence, the purpose of this work was used to study the effect of sediment's characteristics on phosphorus adsorption and desorption. The experiment uses open channel model, instead of conventional shaking flask. The phosphorus concentration of water will be periodically sampled and analyzed. Secondary dynamics equation and Elovich equation were used to stimulate the process. The results showed that shorter balance time attribute to smaller particle size and higher sediment's concentration. Finally, the influence of different equation on phosphorus adsorption stimulation would discuss in this work.
