It was shown thatsulphr vapor is sorbed rapidly and copiously by the zeolites CaA and NaX. The uptake of the large cages in these zeolites is only about 75 of that expected from their volumes. This may be ascribed to steric difficulties encountered in packing large mole cules into the cages. The sulphur uptake of natural chabazite is comparatively slow and limited in extent. Phosphorus is also strongly sorbed by NaX but in this case the approach to equilibrium is slow. Further investigations were conducted on the mercury uptake of silver ion-exchanged zeolites. Large uptakes were recorded with the zeolites having the more open structures and hysteresis loops obtained. The saturation uptakes of mercury are again insufficient completely to fill the structure, and further work is in progress to throw light on this interesting aspect. Author
