Abstract: A novel nickel phthalocyanine/iron oxide nanoparticle (NiTsPc/ION) nanocomposite electrode is proposed for the voltammetric detection of ethinyl estradiol. The method shows a wide linear range (0.07-30 µmolL?? 1, R2 >0.99), sensitivity of 0.308 µAcm?? 2/µmolL?? 1 and limit of detection of 7.8 nmolL?? 1 (3.3 Sb/b). Recoveries are above 95% for quantification in tap and treatment plant water samples and synthetic urine. A single electrode can be used in seven consecutive runs (RSD=2.85%) and responses of different electrodes vary only 7-9%. The excellent sensing performance of the proposed sensor is ascribed to its porous morphology and efficient chargetransfer between ION and NiTsPc.
