摘　　要：在低温条件下,膨润土在超声波下快速合成了4A沸石,分别用粒度、XRD、SEM等进行了表征。结果表明,膨润土在超声波下合成4A沸石的速度是膨润土酸化法的4倍,合成产物的白度为95%,钙离子交换量为328mg/g4A沸石,平均粒径为460nm。Zeolite 4A was quickly synthesized from bentonite in ultrasonic condition at low temperature. The products were characterized by particle size analysis, XRD, SEM and others. The results showed that the crystallization rate of the product synthesized in ultrasonic condition was 4 times faster than that of acidification of bentonite with its whiteness being 95 %, calcium ions exchange capacity 328 mg CaCO3/g zeolite 4A and average particle size 460 nm.
