Abstract

The results of investigation the sensitivity of PD-sensors based on perfluorosulfonic MF-4SC
membranes to novocaine, lidocaine and hydroxonium ions in aqueous solutions are presented in this paper. It
is investigated the materials obtained by casting from a polymer solution and materials obtained by extrusion
of a polymer melt.It was shown, that the membranes obtained by casting from a polymer solution is more
preferable used to increase the sensitivity of PD-sensors to novocaine and lidocaine cations simultaneously
present in solutions. These results are consistent with the sorption studies data of novocaine and lidocaine
ions by MF-4SC membranes and IR spectra of membranes containing organic cations
