The study on the phosphorus loads in the surface sediments in the Nanyang Lake and Weishan Lake showed that the maximum amounts of phosphorus adsorbed(Qmax) are 112.76 mg/kg and 93.91 mg/kg,respectively,and the processes of phosphorus adsorption in the Nanyang Lake and Weishan Lake reach equilibrium after 48 hours.Based on the analysis of characteristics of phosphorus adsorption and phosphorus transformation in the release process,the total maximum amount of adsorbed phosphorus is the sum of Qmax and native...
