Web1 jan. 2001 · This chapter explains the ion exchange capacity in zeolites. In a traditional aluminosilicate zeolite the source of the ion exchange capacity is the extent of isomorphous substitution of Al for Si in the tetrahedral framework. The theoretical exchange capacity thus can be derived from the elemental composition. Web19 dec. 2016 · Density functional theory calculations are used to investigate solid-state ion exchange of copper into zeolites. In particular, the energetic conditions for functionalization of chabazite (CHA) with copper ions from Cu2O(111) via formation of Cu(NH3)2+ are explored.
