ADSORBENTS AND ION EXCHANGERSADSORBENTS AND ION EXCHANGERSCLASSIFICATIONS AND CHARACTERIZATIONSAdsorbents Table 16-3 classifies common adsorbents by structural type and water adsorption characteristics. Zeolite and silicalite adsorbents take advantage of their crystalline structure and/or their molecular sieving properties. The hydrophobic (nonpolar surface) or hydrophilic (polar surface) character may vary depending on the competing adsorbate. A large number of zeolites have been identified, and these include both synthetic and naturally occurring (e.g., mordenite and chabazite) varieties.
