采用红外光谱研究了(NH_4)_2SiF_6处理的KL沸石样品的骨架Si/Al与吸收带频率的关系。在～770cm~(-1)附近吸收带的频率与沸石骨架中Al的摩尔分数X_(Al)(即Al/(Si+Al))间存线形关系:X_(Al)=-7.309×10~(-3)(u_(770-760)+0.3242。这一结果与化学分析结果一致。
Infrared spectroscopy was used to study the relationship between the Si / Al skeleton and the absorption band frequency of (NH_4) _2SiF_6 treated zeolites. The relationship between the absorption band frequency and the mole fraction of Al in zeolite framework, X Al (ie Al / (Si + Al)) near ~ 770cm -1: X - Al = - 7.309 × 10 ~ (-3) (u_ (770-760) +0.3242. This result is consistent with the results of chemical analysis.
