【摘要】 采用等温吸附的实验方法，分别研究了环境因素，其中包括土水比、溶液ｐＨ值、有机阴离子和温度对滇池底泥磷吸附的影响．结果表明：底泥吸磷量随土水比的减少而增大；存在最大吸磷ｐＨ值；有机阴离子能与磷竞争吸附，其竞争能力受底泥颗粒表面性质等因素的影响；底泥对磷的吸附为一吸热过程，温度升高，磷的吸附强度和吸附量增大．更多还原

【Abstract】 On the basis of isothermic dasorption experiments,The influences of environmental factors on phosphate sorption in lake Dianchi are studied.These factors include soil\|solution ration,pH value of the solution,organic ligands and temperature.The amount of P adsorbed increases with the decrease of soil\|solution ratio.There exists a maximum of P adsorption at some equilibrium pH value,which affected by organic matter in sediments.Organic can compete with phosphate for sorption and their competition abilities are closely associated with some characteristics of sediment interface and so on.The amount and the intensity of P adsorbed increase with temperature.更多还原
