Popis: Octadecylamine (ODA)-based Langmuir-Blodgett films modified with metal hexacyanoferrates are promising ion-exchange systems. The analysis of compression isotherms has led to the conclusion that iron and copper hexacyanoferrates are embedded into ODA monolayers. Optimal conditions have been determined for transferring these hybrid films onto a solid substrate by the Langmuir-Blodgett method. The optimal time required for the formation of iron and copper hexacyanoferrates in the monolayer has been established with the use of spectrophotometric measurements. The transfer of ODA monolayers modified with iron and copper hexacyanoferrates onto a conducting substrate has been confirmed by atomic force microscopy. The EMF values of galvanic cells developed based on the ODA/Fe4[Fe(CN)6]3-KCl and ODA/Cu3[Fe(CN)6]2-NH4Cl systems have been shown to be close to the theoretical ones.
