『Abstract
　This study was designed to survey the reservoir sediment properties, assess the phosphorus (P) sorption isotherm, and analyze the relationship between sediment properties and sorption parameters. Physicochemical analysis indicated that sediment from the FUSHI reservoir in Zhejiang Province, China, has similar physical and chemical properties and has been contaminated by P. Sorption isotherm experiments showed that the sorption process could be described by Langmuir and Freundlich models. The parameters of Qmax (Phosphorus sorption maximum) and K (Freundlich adsorption isotherm constant) ranged from 618.98 to 825.70 mg kg-1 and 114.18 to 170.74 l kg-1, respectively. EPC0 (zero P equilibrium concentration) ranged from 0.14 to 0.24 mg l-1, more than the total P concentration in the water of the reservoir. Thus, the reservoir sediment releases P into the water and acts as a “P resource”. The clay, Feo, Alt, and Fet+Alt content were the main active components in P sorption. Qmax had a highly significant positive relationship with some properties and could be estimated by a combination of these.
