摘　　要：以略阳电厂粉煤灰为原料,研究加入Na2CO3煅烧温度、水热时间对粉煤灰物相、合成A型沸石的影响。结果表明在800℃煅烧1h,物相主要为硅铝酸钠。水热8h,合成产物主要为A型沸石。对A型沸石、天然沸石和粉煤灰吸附性能进行了研究,结果表明:合成的A型沸石吸附能力最好,吸附率为99.53%。The effect on calcination temperature added Na2CO3, hydrothermal time for fly ash phase A-type zeolite synthesized is studied by using Lucyang electricity plant fly ash as raw material. The results indicate that the mostly phase of the sample is sodium aluminum silicate, for calcination 1h under 800℃, and A-type zeolite is synthesized after hydrothermal for 8h. And the adsorption ability, of A-type zeolite, the natural zeolite, and fly ash are study. The results indicate that the A-type zeolite adsorption ability is best. It＇s adsorption rate is 99,53%.
