| 摘 要： | 通过研究乌粱素海不同粒径沉积物对磷的吸附动力学曲线和吸附等温曲线,模拟了乌粱素海不同粒级沉积物对磷的吸附过程。研究显示：沉积物对磷的吸附动力学过程包括快吸附和慢吸附,0～45 min内各粒级吸附速率均较高,且不同粒级沉积物对磷吸附的粒度效应明显。二级动力学方程是描述乌粱素海沉积物磷吸附动力学的最优方程,Langmuir...

| Abstract: | Through studying the different particle sizes of Wuliangsuhai Lake sediment phosphorus adsorption kinetic curve and adsorption isotherm curve,it is simulated the phosphorus sorption process of sediments with different grain level from Wuliangsuhai Lake of the sediment.Research shows that the phosphorus adsorption kinetic process including fast adsorption and slow adsorption,within 0～45 min each grain grade absorption rate of each grain grade is higher,and the phosphorus adsorption effect of the sediment with different grain grade is obvious.Secondary dynamic equation is the optimal one to describe Wuliangsuhai Lake sediment phosphorus adsorption kinetics,the optimal Langmuir and Freundlich models can better fit phosphorus sorption isotherm of sediments with different grain level from Wuliangsuhai Lake.The order of adsorption,absorption rate and adsorption efficiency from large to small is as below: <63,63～125,125～250,>250 μm. |
