Influence of electrodeposition potential on composition and ion exchange of polypyrrole films in aqueous hexafluoroaluminate featured by EQCM molar mass to charge factors

► A concise molecular approach to the EQCM gravimetric analysis is presented. ► Synthesis and ion-exchange processes of a polymer in presence of biologically important ions are analysed. ► Chemical and structural compositions in a course of a growth process of polypyrrole are investigated.
