| 摘 要： | 通过对改性海泡石的热力学性能研究,确定了改性海泡石对磷进行吸附的吸附容量、去除率和改性海泡石用量的关系。根据实验数据求解出吸附等温方程并绘制出等温吸附曲线。对等温吸附曲线进行拟合并比较相关系数的大小,得到改性海泡石的等温吸附方程。它符合修正后的Freundlich等温吸附方程:qe=10.4 4 Ci1.148 29.90。此方程较精确地描述了改性海泡石对P O34--的吸附量随浓度的变化,为改性海泡石的工业化除磷应用提供了理论依据。

| Abstract: | The paper studied the energetics property of modified sepiolite.The connection between adsorption capacity,removel ratio and the quantity of modified sepiolite Were confirmed.Using the data of experiment,the isothermal adsorptive equation was determined and isothermal adsorptive curve was drawed.The isothermal adsorptive equation of modified sepiolite was made by fitting the isothermal adsorptive curve and comparing the correlative coefficient.It was about the same as modified Freundlich isothermal adsorptive equation: 1qe=10.4 4 Ci1.48 29.90.It exactly described the connection between concentration and the adsorption capacity to phosphorus of modified sepiolite.The experiment results could offer theoretics foundation in a certainty for industrialized application of modified sepiolite. |
