★ 3.5 (fi 6) (either term or Spring/Summer, 3-1s-0) Structures and properties of molecular sieves and related materials. Applications of molecular sieves in separation processes based on molecular size differences as well as thermodynamic interactions between active surfaces and adsorbates. Molecular sieves in purification processes based on cationic exchange reactions and selective adsorption. Molecular sieves as catalysts. Prerequisites: CHEM 105 and CH E 243.
