That is very nice. Which zeollite are you referring to exactly ? The 4A, 5A, 12A, or some other ? As you know, the term zeolite is generic for molecular seives developed by Union Carbide in the 40's and 50's, and these aluminosilicates have different pore sizes, depending on use and application. Thus, the word zeolite does not refer to a single one of these. Do you know which zeolite you have in your store, and what its pore size is ?
