摘要：

The alkali metal ion exchange reaction on cubic ammonium molybdate (CAM) cation exchanger was studied in acidic as well as alkaline media. The ion-exchange reaction and TPD-Mass thermogram of CAM indicated the presence of structural NH4+ as interstitial solid solution. The structural NH4+ in the H+ form of CAM (H-CAM) was efficiently exchanged with K+ as compared with other alkali metal ions in the equilibrated solutions. The exchanger was observed to be stable in acid medium, however structural transformations were observed at high pH. The presence of K+ and Cs+ at high pH could act as ''Structure Building Ions'' for CAM or H-CAM.
