对累托石对水中扑尔敏的吸附性能进行了研究,系统地研究了吸附时间、溶液浓度、pH值对其吸附行为产生的影响。实验结果表明：累托石对扑尔敏的吸附速率先快速增大后趋于平缓,反应系统达到吸附平衡的时间约为22 h;在等温吸附研究中,室温下累托石对扑尔敏的最大吸附量为121.76 mg/g,吸附等温线方程符合Langmuir等温模型;吸附行为符合拟二级动力学方程;在pH值为2～8时,吸附量随pH值的升高而增大。

This paper investigated the removal efficiency of rectorite on chlorpheniramine（CPM）.Adsorption of CPM by rectorite was discussed under different time,concentration and pH conditions.Experimental results showed that the removal efficiency on CPM increased quickly first then slowed down with time;and the adsorption equilibrium reached in 22 hrs.Based on the Langmuir model analysis,the maximum adsorption capacity of rectorite on CPM is 121.76 mg/g at room temperature.Besides,the adsorption kinetics could be better described by the pseudo-second-order-model,and the optimal adsorption occurred in alkaline condition.
