摘要
从热力学和动力学两个方面讨论了交联膨润土吸附剂对磷的吸附特性，吸附等温式符合Ｌａｎｇｍｕｉｒ公式，通过吸附动力学公式计算扩散活化能为６．１６１ｋＪ／ｍｏｌ，这表明吸附过程受扩散控制．
The adsorption of crosslinked bentonite for phosphate in solution has been studied in terms of thermodynamics and kinetics.The adsorption process conforms to the Langmuir adsorption isotherm equation,according to the equation of thermodynamics on adsorption of PO_4~3-.The activiation energy for the adsorption of PO_4~3-on adsorbent BA is 6.161 kJ/mol.The result shows that the process of adsorption of PO_4~3- by adsorbent BA is a particle diffusion control process.
