Evaluation of cadmium hexacianoferrate(III) as a microporous material

Abstract

The properties of cadmium hexacyanoferrate(III), Cd 3[Fe(CN) 6] 2, as a microporous material were evaluated from adsorption data of CO 2, N 2 and water vapor. The adsorption isotherms were interpreted according to the Dubinin–Radushkevich and Dubinin–Astakhov models. The adsorbate–adsorbent interactions during the activation and the adsorption processes were monitored by XRD, IR and Mössbauer techniques where the adsorption of propanol, ethanol and diethyl ether was also considered. As a measure of the adsorbate–adsorbent interactions, calculations of the adsorption isosteric heats were also carried out.
