Phosphorus release potential and pollution characteristics of sediment in downstream Nansi Lake, China

Zhijian LI, Qinyan YUE, Baoyu GAO, Yanwen WANG, Qing LIU

Frontiers of Environmental Science & Engineering 2012, Volume 6, Issue 2,   Pages 162-170 doi: 10.1007/s11783-011-0313-7

Abstract: Kinetics and isotherms of adsorption/release of sedimentary phosphorus were studied to determine equilibriumphosphate concentration (EPC ) and release potential.By comparing EPC and SRP of water, the status (adsorption, releasing or in equilibrium) of sedimentsediments at S9, S10, and S12, where the EPC s were approximately equal to the SRPs, were in impermanent equilibriumstatus of phosphorus, the sediments can be likely to release phosphorus to the water column once the equilibrium
