Abstract

We developed a potentiometric ion-selective electrode (ISE) for detecting the food dye sunsetyellow (SY). Sunset yellow-Methyltrioctylammonium chloride ion pairs were synthesized.The ion pair that was synthesized was employed as ionophorein the configuration of theelectrode membrane. PVC membrane ion-selective electrodes in various compositions wereproduced using the ion pairs that were synthesized and then, potentiometric performancecharacteristics of these electrodes were investigated. It was determined that the electrode withthe composition of 3.0 % sunset yellow-Methyltrioctylammonium (Sunset-MTOA) ion pair,64.8 % nitrophenyloctyl ether (NPOE), 32.0 % polyvinylchloride (PVC) and 0.2 % potassiumtetrakis (4-chlorophenylborate) (KTpClPB) demonstrated the best potentiometric performanceproperties. The linear range, slope, limit of quantification, pH range, and the response time ofthe 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.
