Abstract In this study, a new lawsone derivative molecule (2) was synthesized, and sensors were prepared using it as electroactive material (ionophore). These exhibited selectivity towards Cr 3+ ions among different cationic species. The polymer membrane contained 3.0% ionophore, 64.0% dibutyl phthalate (DBP), 32.0% polyvinylchloride (PVC) 1.0% lipophilic additive (KT p ClPB). For novel potentiometric sensor, linear concentration range, Nernstian slope, detection limit, pH working range response time determined 1.0 × 10 −1 –1.0 −7 M, 21.8 ± 1.7 mV/decade, 7.65 −8 5.0–9.0 8 s, respectively. analytical application of the sensor carried out by determining in samples to which certain amounts added. newly developed able determine with very high recoveries.
