Potentiometric Determination of Lead(II) Ions Based on 1,4–Naphthaquinone Derivative Molecule

Abstract

Herein, the ionophore properties of a 1,4–naphthoquinone derivative molecule was investigated. For this purpose, polymer membrane ion selective sensors were prepared and their potentiometric performance characteristics were studied. The prepared sensors exhibited a very high selectivity against Pb(II) ions. The novel Pb(II)–selective potentiometric sensors had a low detection limit (LOD) of 8.38×10-7M in a wide concentration range of 1.0×10-6–1.0×10-1 M. The newly developed sensors had a wide pH working range of 4.0–10.0 and a fast response time of 5 seconds. Finally, the newly developed Pb(II)–selective potentiometric sensor was able to determine Pb(II) ions in various samples with very high recoveries.
