ABSTRACT
The most important technique used to modify zeolites is ion exchange. This chapter will review the ion-exchange properties of aluminosilicate zeolites with some emphasis on the problems and pitfalls encountered by this author. The techniques used to collect and analyze ion exchange data will be described. The data will be presented in the form of ionexchange isotherms. These isotherms can be used to calculate thermodynamic quantities in the equilibrium case (1), in the design of experiments (2), and in commercial ion-exchange processes (2).
