The study of permeation of Aromatic compounds across parchment-supported membrane treated with Prussian blue is presented. The skin layer of the metal hexacyanoferrate membrane consists of a network structure could be selectively used with defined pore size in the nanometer range to permeate molecules with different size molecules. In order to demonstrate a possible sieving of molecules, we have investigated the permeation of a variety of aromatic compounds such as aniline (An), phenol (Ph), and naphthalene (Np). For these neutral compounds, a size-selective transport was found. Size lead to a separation factor α(An/Ph) of 1.5 and α(An/Np) of 4 respectively. Finally, it is demonstrated that purely inorganic membrane of Prussian Blue (PB) can be prepared upon adsorption of ferric ion and hexacyanoferrate on porous support.
