Spectrofluorimetric studies on the binding properties of Tris (3–(2–hydroxyacetophenone)propyl) amine) (L) toward different heavy metal ions in acetonitryl solution revealed its selective 1:1 complexation with Zinc ion. Consequently, L was used as a suitable ionophore for the preparation of new plasticized PVC membrane–selective electrodes for the determination of Zinc ion. The sensor exhibits a Nernstian response for Zn(II) over a wide concentration range (2.0×10–7–1.0×10–1 M) and detection limit of (9.6 ×10–8 M). The best performance was obtained with a membrane composition of PVC (30%), orthonitrophenyloctyl ether (o–NPOE) (64%), ionophore (L) (5%) and Potassium tetrakis(KTpCIPB) (1%). The sensor exhibits the advantages of fast response time (12 seconds),operational lifetime (24 weeks) and good selectivity co–efficient for Zn(II) over an alkali, alkaline earth and transition metal ions. The electrode was used as indicator electrode inpotentiometric titration of Zn(II) with ethylenediaminetetraacetic acid (EDTA) and in thedetermination of Zn2+ ion in real samples.
