| Özet |
| In this study, a simple and highly selective potentiometric sensor has been developed for the determination of cobalt(II) ions based on a poly(vinly chloride) (PVC) membrane. As an ionophore, a hydrazone derivative molecule (3) was synthesized for the first time, and its characterization was completed using NMR, FT-IR and Q-TOF spectroscopic techniques. The developed sensor works well in the linear concentration range of 1.0×10−6–1.0×10−1 Μ with Nernstian slope of 28.6±1.7 mV/decade of activity. The developed cobalt(II)–selective sensor has a low detection limit of 3.09×10−7 Μ, and a very fast response time of 5 seconds. The sensor, which exhibits a highly selective behaviour towards cobalt(II) ions compared to other metal cations, works in the pH range of 6.0–10.0 without being affected by changes in pH. The developed sensor could be used as an indicator electrode in potentiometric titration of Co(II) ions with EDTA. Finally, the developed cobalt(II)-selective sensor was successfully used for the determination of Co(II) in various water samples. |
