Abstract

Equilibrium exchange isotherms were determined for the exchange of Cu2+ with NaZSM-5 at varying Cu(Ac)2 concentrations in solutions of constant volume and zeolite weight. At low Cu2+ levels the solid scavenged all the copper ions. When copper could be detected in the equilibrated solutions, “overexchange” was observed. The extent of “overexchange” was higher at pH ≈ 6 than at pH ≈ 4. These results were analyzed in relation to catalytic activity.
