摘要:

Liquid-membrane electrodes sensitive to scopolamine+and N-butyl scopolammonium+are described for the direct or indirect assay of scopolamine hydrobromide and N-butyl scopolammoniumbromide, respectively, in pharmaceutical preparations. All electrodes exhibit a linear response to respective organic cation over the range of lo−1to lo−4M. No interference from the common imgredient substances was observed.
