We developed a potentiometric ion-selective electrode (ISE) for detecting the food dye sunset yellow (SY). Sunset yellow-Methyltrioctylammonium chloride ion pairs were synthesized. The ion pair that was synthesized was employed as ionophorein the configuration of the electrode membrane. PVC membrane ion-selective electrodes in various compositions were produced using the ion pairs that were synthesized and then, potentiometric performance characteristics of these electrodes were investigated. It was determined that the electrode with the composition of 3.0 % sunset yellow-Methyltrioctylammonium (Sunset-MTOA) ion pair, 64.8 % nitrophenyloctyl ether (NPOE), 32.0 % polyvinylchloride (PVC) and 0.2 % potassium tetrakis (4-chlorophenylborate) (KTpClPB) demonstrated the best potentiometric performance properties. The linear range, slope, limit of quantification, pH range, and the response time of the electrode were determined as 1.0 × 10-5-5.0 × 10-2 M, 23.6 mV,1.0 × 10-5 M,6.4-9.1, and ≈ 5 sec, respectively. The electrode exhibited a highly repeatable potentiometric response
