In this study, a new sulfonyl hydrazone derivative molecule was synthesized, and its characterization was performed using several spectroscopic methods (1H-, 13C NMR, FT-IR and Q-TOF). New potentiometric sensors were developed using this molecule, and subsequently, their potentiometric performance properties were investigated. Based on the data obtained, we found that the prepared sensors are selective to Pb2+ ions. These novel lead(II)-selective sensors had a low detection limit of 2.89 x 10-6 M, and a Nernstian response (27.7 +/- 1.3 mV/decade) over a wide concentration range of 1.0 x 10-5-1.0 x 10-1 M. They were also highly reproducible, selective and able to work in a wide pH range (3.0-9.0) without being affected by the changes in pH. We showed that these potentiometric sensors can detect Pb2+ ions with very high recoveries when applied to real samples. In conclusion, we here report the synthesis and characterization of a new molecule and its potentiometric sensor properties.
