Abstract: | The sorption of galactose by Na-Y, K-Y and Ba-Y zeolites has been investigated by isopiestic equilibration at 25°C. The equilibrium galactose and water contents of the zeolites were determined for water activitiesa
w in the range 0.111 <a
w < 0.98. It was found that the maximum uptake of galactose U
0
G
(observed fora
W 0) was highest for Na-Y and least for Ba-Y. In contrast at high water activities the galactose uptake was highest for Ba-Y and least for Na-Y. |
