title: [Ion-selective electrodes with a liquid membrane for determining N-butylscopolammonium bromide].
abstract: Two ion-selective electrodes with liquid membrane for N-butylscopolamonium bromide are described, with N-butylscopolamonium tetraphenylborate (I) and N-butylscopolamonium reineckate (II), respectively, solved in benzylic alcohol as electroactive material. These electrodes have a linear response in the concentration range of 10(-2)-10(-6) M N-butylscopolamonium bromide, with the detection limit of 10(-7) M for both electrodes. These electrodes were used with good results for quantitative assay by direct potentiometry of injectable solutions of N-butylscopolamonium bromide.
