采用ＣＯ２－ＴＰＤ及Ｈａｍｍｅｔ指示剂法测定了ＫＮＯ３／Ａｌ２Ｏ３及Ｋ２ＣＯ３／Ａｌ２Ｏ３样品的碱量和碱强度。当ＫＮＯ３、Ｋ２ＣＯ３的负载量低于其单层分散阈值时，能在Ａｌ２Ｏ３上均匀分布并产生强度（Ｈ－）为１８．４的强碱位；高于其单层分散阈值后则能生成强度（Ｈ－）为２７．０的超强碱位。
The alkalinity and alkali strength of KNO3 / Al2O3 and K2CO3 / Al2O3 samples were measured by CO2-TPD and Hammet indicator method. When the loadings of KNO3 and K2CO3 are lower than their monolayer dispersion thresholds, they can distribute uniformly on Al2 O3 and produce strong base with intensity (H-) of 18.4. Above the monolayer dispersion threshold, the strength can be generated (H-) of 27.0 super base.
