Popis:	New plastic membrane electrode for terbutaline sulfate (Tr 2 SO 4 ) based on terbutalinium phosphotungstate (Tr-PTA) was prepared and fully characterized in terms of composition, life span, pH and temperature and then applied to the potentiometric determination of the terbutalinium ion in its pure state and pharmaceutical preparations in batch and flow injection conditions. The selectivity of the electrode towards many inorganic cations, sugars and amino acids was also tested. The results of the potentiometric determination of the drug in its pure state and pharmaceutical preparations were then compared to those obtained from the conductimetric determination of the drug. The solubility product of (Tr-PTA) was also calculated conductimetrically.
