| Özet |
| In this study, a new lawsone derivative molecule (2) was synthesized, and sensors were prepared using it as electroactive material (ionophore). These sensors exhibited selectivity towards Cr3+ ions among different cationic species. The polymer membrane contained 3.0% ionophore, 64.0% dibutyl phthalate (DBP), 32.0% polyvinylchloride (PVC) and 1.0% lipophilic additive (KTpClPB). For this novel potentiometric sensor, linear concentration range, Nernstian slope, detection limit, pH working range and response time were determined as 1.0 × 10−1–1.0 × 10−7 M, 21.8 ± 1.7 mV/decade, 7.65 × 10−8 M, 5.0–9.0 and 8 s, respectively. The analytical application of the sensor was carried out by determining Cr3+ in samples to which certain amounts of Cr3+ ions were added. The newly developed sensor was able to determine Cr3+ ions in different samples with very high recoveries. |
