摘要
以亚甲基蓝(MB)为吸附质,通过静态吸附实验研究铝硅酸盐矿物吸附行为。结果表明:pH、吸附时间、吸附剂用量是影响MB吸附行为的主要参数;pH在8左右铝硅酸盐矿物对亚甲基蓝吸附效果最佳;亚甲基蓝在铝硅酸盐矿物表面吸附行为可用Langmuir吸附等温方程描述。说明铝硅酸盐矿物是一种有效吸附剂,可以去除有机废水中的亚甲基蓝。
The aim of this study is to understand the adsorption behavior of methylene blue （MB） on the surface of aluminum silicate and optimize the removal of MB from wastewater. The adsorption of MB by aluminum silicate is found out to strongly depend on pH, contact time and adsorbent dosage. When the pH reaches around 8, aluminum silicate has optimal effect to adsorb MB. The adsorption results can be described by the Langmuir-type adsorption isothermal equation and the adsorption mechanism is discussed. The experiment results indicate that aluminum silicate is an effective adsorbent.
