摘　　要：在粉煤灰理化特性分析的基础上,对粉煤灰进行了物理激发和化学激发.研究结果表明:物理激发和化学激发均能提高粉煤灰的吸附活性.化学激发方法在反应温度为90℃、反应时间为12h、灰钙比为5、水固比为15时,粉煤灰的吸附活性提高最大.After having analyzed the physicochemical properties of fly ash,we took physical activation and chemical activation on it.The result shows that both physical activation and chemical activation can enhance the adsorption activity of fly ash.The adsorption activity of fly ash reached the maximum while the reaction temperature was 90 ℃;the reaction time was 12 h;the weight ratio of fly ash and Ca（OH）2 was 5;the weight ratio of water and solid amount was 15.
