摘要：
Potentiometric detection of salbutamol sulphate Sl(2)SO(4) using electrodes containing its ion-exchangers with phosphotungstic; phosphomolybdic acid or a mixture of both was applied in flow injection systems in the Nernastian range of the electrodes response. The selectivity of these electrodes towards different cations was studied in comparison to that obtained in batch conditions. The method was then used to determine the drug in its pharmaceutical preparations.
