| 摘 要： | 制备了Fe、Al柱撑膨润土,研究了其对水溶液中锌离子的吸附去除性能,结果表明:Fe、Al柱撑膨润土对水溶液中的锌离子有很好的去除效果,当其用量为0.5 g时,水溶液中锌离子的吸附去除率达到93.6%;Fe、Al柱撑膨润土对水溶液中的锌离子的吸附在60 min达到平衡;溶液pH对水溶液中锌离子的去除有一定的影响,在中性和弱碱性条件下的去除率大于酸性。平衡吸附量与平衡质量浓度之间的关系符合Freundlich和Langmuir等温吸附方程所描述的规律。

| Abstract: | Fe,Al pillared bentonite was prepared and the adsorption of Zn2 by it from aqueous solution was studied.The result show that Fe,Al pillared bentonite have a good effect on the adsorption of Zn2 from aqueous solution;when doping the solution with 0.5 g bentonite,93.6% of Zn2 can be adsorbed.The adsorption of Zn2 reaches equilibration by 60 minutes;a little more adsorption can be gained in neutral and weakly alkaline solution than acid solution condition;the relationship between adsorbing capacity(qe) and equilibrium mass concentration(pe) is in accordance with the isothermal adsorption equations of Freundlich and Langmuir. |
