| Research Abstract |
In this research, polyvinylchloride(PVC) membrane containing plasticizer, supporting salt, an ionophore was used as an ion-selective electrode(ISE), and we demonstrated that K^+, Li^+, Ca6<2+>, Mg6<2+> can be detected by using these electrode through ion transfer voltammetry. It is shown that the facilitated ion transfer processes across the interface between PVC and water(W) are electrochemically quasireversible, and from digital simulation, the rate constant of the facilitated ion transfers are in the range of 0. 01-0. 001 cm s^<-1>. We also confirmed that these ISE can work in a diluted serum solution.
