The formation of complexes of CO2+ ion with H2O molecules in the framework of synthetic molecular sieve A, at different stages of redhydration have been investigated by diffuse reflectance spectroscopy. The results showed that Co1A, Co1.7A, Co2.8A and Co3.4A regained their initial structures after complete rehydration. The spectrum of fully rehydrated Co4.9A was nearly similar as of its fully hydrated sample [1], except a weak band at 17300 cm-1 instead of weakly emerged shoulder. The rate of rehydration was observed to decrease on increasing the Co2+ ion loadings in the zeolite.
