ABSTRACT:
A method is provided for the nondestructive trivalent cation ion exchange of molecular sieves comprising ion exchanging at least one molecular sieve with at least one trivalent cation, wherein the ion exchange is performed at ion exchange conditions with an ion exchange solution comprising the trivalent cation, a trivalent cation complexing agent, and a suitable amount of a hydroxide-producing component to form an ion exchange solution having a pH ranging from about 4 to about 8.
