以粉煤灰（FA）经碱熔融和酸处理制得活性粉煤灰（AFA），并将其用于模拟废水中活性深蓝K-R的吸附，探讨了AFA的制备条件和影响吸附的因素。结果表明：在m（Na2CO3）∶m（FA）为1∶5，焙烧温度为850℃，HCl浓度为4 mol/L ，搅拌溶解温度为80℃的制备条件下，所制得的AFA对3500 mg/L活性深蓝K-R的吸附量为335.98 mg/g，活性深蓝K-R去除率达94.5%；染料起始浓度、pH、吸附时间和温度均对吸附效果产生影响；吸附动力学可用准二级吸附动力学方程进行描述（R2=1.000）；等温吸附符合Langmuir方程。 AFA可有效去除水溶液中高浓度的活性深蓝K-R。

Activated fly ash (AFA) has been prepared by fly ash which was alkali-melted and acid treated. It can be used for the adsorption of reactive deep blue K-R from simulated wastewater. The optimal preparation conditions of AFA and the factors that affect adsorption are discussed. The results show that when m(Na2CO3)∶m(FA) is 1∶5, calcination temperature 850℃,HCl concentration 4 mol/L,and stirring solution temperature 80℃,the adsorption capacity of prepared AFA for 3 500 mg/L of reactive deep blue K-R is 335.98 mg/g,and the removing rate of reac-tive deep blue K-R reaches 94.5%. The initial concentration of dye,pH,and adsorption time and temperatare all have effects on adsorption effectiveness. Adsorption kinetics can be described by pseudo-second-order kinetic equa-tion (R2=1.000). The adsorption isotherm agrees with the Langmuir equation. AFA is an effective adsorbent for the removal of reactive decp blue K-R with high concentration from aqueous solution.
