The influence of lanthanum ions on the framework silicon, aluminum and extra-framework aluminum of LaDAlY zeolites has been studied by using 29Si, 27A1 MAS NMR and static 27Al NMR with acetylacetone treatment.

• 用~(29)Si(~(27)Al)MAS NMR和辅加乙酰丙酮(acac)处理样品的静态~(27)Al NMR研究了镧离子对脱铝Y型沸石(DAIY)骨架硅、铝和非骨架铝(EFAL)的影响.
