摘　　要：随着当代工业的发展,以煤炭为主的化石能源使用日益剧烈,以粉煤灰为代表的工业废渣严重污染环境。研究以粉煤灰为原料,通过碱熔融水热合成法,制备了一种耐高温、耐酸碱,具备独特空穴骨架和较大比表面积的磁性A型沸石,并通过XRD、FT-IR、XRF、SEM等手段进行了表征。吸附性能测试中,以甲基蓝溶液模拟工业废水,使用磁性A型沸石样品进行吸附性能研究,实现913. 25mg/g的最大实际吸附量。With the development of contemporary industry,coal-based fossil energy use is increasingly fierce,with fly ash as the representative of the industrial waste greatly affected the environment.In the study,a kind of magnetic type A zeolite with high temperature,acid and alkali resistance and unique specific pore skeleton and large specific surface area was prepared by alkali-melting hydrothermal synthesis,XRD,FT-IR,XRF,SEM and so on.In the adsorption performance test,methyl blue solution was used to simulate industrial waste water,and magnetic A zeolite sample was used for adsorption performance study to achieve the maximum actual adsorption capacity of 913.25 mg/g.
