通过离子交换方法讨论了Li+交换对Na—LSX分子筛的影响。并利用XRD、SEM、FT-IR和TG-DTA对离子交换后的样品进行了表征,考察了Na-LSX分子筛在Li+离子交换前后其骨架结构和织构性能的变化情况。
XRD, SEM, FT-IR, and TG-DTA techniques were employed to characterize the structures and performance of LSX. With the increasing of the Li+ ion-exchange degree, it was foupded that some properties and the framework structure of LSX were changed.
