Abstract

In this study, a new potentiometric sensor selective for copper(II) ions was developed. A semicarbazone derivative molecule synthesized as an ionophore was used in the composition of the new sensor. The proposed polymer membrane sensor had a wide linear operating range of 1.0×10-5–1.0×10-1 M, a low detection limit of 4.2×10-6 M, and a near-Nernstian response. The new copper(II)-selective sensor had a wide pH range, fast response time, good selectivity and good reproducibility. The sensor, whose potentiometric performance characteristics were successfully completed, was able to determine copper(II) ions in water samples with very high recoveries.
