Abstract
A plastic membrane electrode based on phenylephrine-tetraphenylborate ion association shows a Nernstian response to both ephedrinium (Ep+) a nd silver (Ag+) cations over the concentration ranges 2 x 10(-5)-10(-1 ) m and 10(-5)-10(-1) m for Ep+ and Ag+, respectively. The performance characteristics of the electrode were investigated. The electrode pro ved to be an excellent potentiometric sensor for the determination of Ep-hydrochloride in its pure solutions and pharmaceutical preparations using the extrapolation method and potentiometric titration using a s tandard solution of AgNO3.
