%X Phosphorus sorption (P sorption) on surface sediments in three shallow lakes in Yangtze River Basin was studied. The results indicated that P sorption mainly occurred within 2 h during the fast sorption process. P sorption on the sediments could be well fitted to the Langmuir isotherm equation modified with the native adsorbed phosphorus (NAP). The P sorption capacity and NAP varied from different sediment samples, depending on the site-specific environmental conditions. And the P sorption capacities were closely related to the specific surface area,the contents of iron/aluminum (oxy) hydroxides and organic matter. The correlation coefficients of on thes components were 0.92, 0.98, 0.78 and 0.92, respectively. The contents of iron/aluminum (oxy) hydroxides were also closely correlated with the contents of organic matter. P sorption was slightly affected by Zeta potential of sediments.
