摘要
采用聚合硫酸铝对蒙脱土进行改性,比较钠基蒙脱土和改性蒙脱土对染料的吸附性能,得到两种吸附剂的加入量对染料去除率的影响、吸附动力学曲线、等温吸附曲线。结果表明改性蒙脱土的吸附能力远远大于钠基蒙脱土。
The modified montmorillonite has been prepared with polyaluminium sulphate. Its performance of adsorbing dyestuff has been compared with Na-montmorillonite. The effect of the dosages of the two kinds of absorbents on the removal rate of dyestuff, the adsorption kinetics curve,and absorption isotherms curve are obtained. It shows the adsorption capacity of modified montmorillonite is evidently higher than that of Na-montmorillonite.
