| 摘 要： | 以盐酸和硫酸作为改性剂，对粉煤灰进行改性。通过正交实验得到最佳改性粉煤灰制备条件为：V（盐酸）∶V（硫酸）=1∶5，浸泡时间6h，活化时间6h，活化温度250℃。在初始苯胺质量浓度为200mg/L、氯化钠质量分数为15%、吸附时间为60min的条件下，采用在最佳条件下制备得到的改性粉煤灰对苯胺进行吸附，吸附量可达4.16mg/g。采用Freundlich方程可更好地对改性粉煤灰吸附苯胺的过程进行拟合。

| Abstract: | Fly ash was modified using HCl and H2SO4 as modifiers. The modification conditions optimized through orthogonal tests are as follows：V(HCl)∶V(H2SO4)=1∶5,soaking time 6 h,activation time 6 h and activation temperature 250 ℃. When the initial aniline mass concentration is 200 mg/L,the NaCl mass fraction is 15% and the adsorption time is 60 min,the adsorption capacity of the modified fly ash to aniline can reach 4.16 mg/g. The adsorption of aniline on the modified fly ash is fit better for Freundlich equation. |
