Stable films of zinc-hexacyanoferrate: electrochemistry and ion insertion capabilities

Abstract A stable film of zinc hexacyanoferrate is deposited on a GC (glassy carbon) substrate following specific electrochemical protocol. The electrode maintains its characteristic even after dry and wet processes. SEM characterization confirms the cubic morphology materials IR suggests presence Fe II -C-N-Zn structural unit. indicates very good stability film, thus opening application in ion exchange system. focus monovalent, divalent, trivalent ions. These results, low toxicity, cost make films promising candidate for many applications.
