| 摘 要： | 对于高钙质湖泊来说,水体中钙离子对沉积物磷吸附特征影响非常重要.文章选取北方典型湖泊沉积物进行了吸附实验并通过Langmuir等温吸附模型线性拟合,研究了沉积物的等温吸附特性及水溶液中钙离子浓度对沉积物吸附的影响.沉积物最大吸附量(Qmax)在208.77～450.45 g/kg之间.Qmax与沉积物中Fe和Al的含量...

| Abstract: | Effect of calcium in lake on phosphorus adsorption characteristics is very important for high calcium lake.Adsorption characteristics of phosphorus and effect of calcium on sediments of typical lake in North China were investigated with Langmuir model.Results showed that the maximum adsorption amount varied from 208.77~450.45g/kg,that was highly correlated to the content of Fe and Al in sediment with coefficient of 0.767,which indicated Fe and Al in sediments were comparatively important for adsorption of p... |
