Voltammetric Determination of Ethalfularin on Glassy Carbon Electrode and Nafion-Graphene Modified Glassy Carbon ElectrodeKoçak, BernaKimya, AnalitikIn this study, the electrochemical behavior of ethalfluraline (ETF), a dinitroaniline group herbicide, onglassy carbon electrode(CKE) and nafion-graphene modified glassy carbon electrode(N-GR /CKE) was investigatedby cyclic voltammetry(CV). Voltammetric determination of ETF was examined by differential pulsevoltammetry(DPV). Two peaks observed at -0.942V(1st peak current) and -0.768V(2nd peak current) during thepotential scan of EFT by DPV method in pH 7 phosphate buffer solution between 0 and -1.5V on CKE and at -0.674V(1st peak current) and -0.563 V(2nd peak current) during the potential scan on N-GR/CKE. After determining theoptimum experimental conditions of ETF on CKE and N-GR /CKE, calibration line, working range, limit ofdetection(LOD), limit of quantification(LOQ), intra-day and inter-day repeatability were determined. In addition, the interference effect of some cations(Cu²⁺, Ni²⁺, Co²⁺, Ca²⁺, Pb²⁺) on N-GR/CKE was also investigated.The results show that EFT can be determined in real samples(water and soil) using CKE and N-GR/CKE.2021Articlehttps://rdlopen.rawdatalibrary.net/r/munzur/6640https://doi.org/10.21597/jist.8469932146-0574trIğdır Üniversitesi Fen Bilimleri Enstitüsü Dergisiinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://munzur-rdlopen.rawdatalibrary.net/tr/items/munzur/6640
