| In this study, an ion–selective electrode was developed for the potentiometric determination of strontium ions. Membrane optimization studies showed that the most suitable membrane composition was 4.0% (w/w) synthesized ionophore, 63.0% (w/w) bis(2–ethylhexyl)sebacate (BEHS), 32.0% (w/w) poly(vinyl chloride; PVC) and 1.0% (w/w) potassium tetrakis(p–chlorophenyl)borate (KTpClPB) in terms of potentiometric performance characteristics. The electrode, which exhibits a stable potentiometric behaviour, shows a linear response in the concentration range of 1.0 × 10−5 – 1.0 × 10−1 mol L−1 (R2 = 0.998). The electrode has a detection limit of 7.94 × 10−6 mol L−1 and a fast response time of 7s. The electrode exhibits selectivity against Sr(II) ions in the presence of some cationic species and works without being affected by pH changes in the pH range of 6.0–9.0. The proposed electrode … |
