cation and preventing interaction with adsorbates such as nitrogen, oxygen, and argon. A schematic of the sodalite cage and double six-ring (hexagonal prism) showing the sites of lithium is shown in Figure 2. Li54.0Ag41.8Na0.2-LSX Structure The results of the Rietveld refinement for the Li54.0Ag41.8Na0.2-LSX zeolite are shown in Table 4; and the agreement of the experimental and the refined model were very good (χ2 = 1.456). The lithium cations of this sample were located only in the six- ring sites, SI′ and SII. No site SIII supercage lithium cations were located. As with the near-fully Li-exchanged sample, an over-population of Li was located at the SII site (40.3 cations). However, if one assumes that only 32 Li cations are located at this site, the total is very near the expected total value of lithium (55.4 of the expected 54.0). Because of this, it is likely that the GSAS suite, using Rietveld refinement, consistently over estimates the population of SII lithium. Most of the silver was found in the SIII supercage sites (approximately 80% of the total found). This is an indication that the smaller lithium cations, when in competition with silver cations, prefer to occupy the six-ring sites. However, it may also be the result of the order of ion-exchange. Since the low silica X zeolite was first ion- exchanged with lithium and then subsequently with silver, the lithium cations had the first opportunity to occupy the more energetically favorable six-ring sites. If the ion- exchange was done in the opposite order, silver cation may very well have retained occupancy of the six-ring sites (for silver, those would include SI, SI', SII', SII, and SII*, see Figure 3). 94PDF Image | PSA USING SUPERIOR ADSORBENTS
