A natural clinoptilolite from Turkey [1] has been tested for a variety of potential air purification/ separations. Henry's law constants for adsorption of CO2, CO, NO, and N2 were measured on clinoptilolite, 4A and 5A zeolites, and H - Mordenite over various temperature ranges between 243 and 473 K. Equilibrium separation factors were calculated for CO/N2 and NO/N2 systems on the various zeolites. Low concentration separation factors for the CO/N2 and NO/N2 systems ranged from 5 to 20 for clinoptilolite. Pure component adsorption isotherms were determined for N2 and CO2 on clinoptilolite at 303 K and up to 1 atmosphere. Binary adsorption isotherms for the CO2/ N2/ clinoptilolite system were predicted using the extended Langmuir equation, the Ideal Adsorbed Solution Theory (IAST), and the Flory - Huggins and Wilson forms of the Vacancy Solution Theory (FH-VST and W-VST, respectively).
