摘　　要：通过对蒙脱石的改性处理,制备了强化铁铈-纳基蒙脱石,并研究了其对水溶液中四环素的吸附行为。结果表明,溶液pH、离子强度和温度对吸附效果均有明显的影响。用Freundlich方程和二阶吸附动力学方程能较好的描述四环素的吸附过程。Montmorillonite adsorbent was prepared by modification with Fe3＋ and Ce3＋. The adsorption dynamics of tetracycline on modified montmorillonite was investigated. The results showed that the pH in the solution, ionic strength and temperature showed significantly influence on the adsorption. The removal of tetracycline decreased with increasing pH, ionic strength, and temperature as well. The adsorption process can be described by the Freundlich and second-order dynamics equations.
