title: [Membrane-selective electrode for atropine assay].
abstract: One membrane-selective electrode with PVC matrix for atropine is described, with atropine tetraphenylborate as electroactive material. This electrode has a linear response in the concentration range of 10(-2)-10(-5) M atropine sulphate, with a detection limit of 3.29 x 10(-6) M. This electrode was used with good results for quantitative assay by direct potentiometry and potentiometric titration of atropine sulphate from pharmaceutical formulations.
