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。
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.
