Prussian Blue Analogues for the Separation of Hydrocarbons in Humid Conditions.

The relative affinity of a series of Prussian Blue analogues presenting various chemical compositions for the adsorption of different gases, such as water vapor and hydrocarbons, was studied. The ability of Co[CoIII(CN)6]0.66·5.2H2O for the separation of hydrocarbons in a humid atmosphere was demonstrated.
