| 摘 要： | 制备了Fe-Al柱撑膨润土,研究了其对染料酸性大红的吸附去除性能,结果表明:Fe-Al柱撑膨润土对染料酸性大红有很好的去除效果,当其用量为0.1g时,染料酸性大红的吸附去除率达到92.6%;Fe-Al柱撑膨润土对染料酸性大红的吸附在60分钟达到平衡;pH值对染料酸性大红的去除有一定的影响,在酸性和碱性条件下的去除率大于中性。平衡吸附量qe与平衡质量浓度pe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 acid red by it from aqueous was also studied.The result showed that Fe-Al pillared bentonite had a good effect on the adsorption of acid red from aqueous solution.While dropping 0.1 g,92.6% of acid red was adsorbed.The adsorption of acid red reached balance 60 minutes later.Aqueous solution pH also had a little effect and the adsorption of acid red was higher in acid and alkaline conditions.The relationship between adsorbing capacity(qe)and equilibrium mass concentration(Pe)is in accordance with the isothermal adsorption equations of Freundlich and Langmuir. |
