• [Display omitted] •Ternary metal oxides (TMO) composites prepared by wet-chemical method.•Highly sensitive and selective Bisphenol A (BPA) sensor by I–V method.•Ultra-low detection limit was obtained by 3N/S.•Real environmental samples were analyzed.•Health care and environmental safety A facile wet chemical method in basic medium was used to synthesis the ternary metal oxides (TMO; ZnO.CoO.FeO) composites at low temperature. The calcined TMO was characterized by FESEM, EDS, UV/vis., FTIR spectroscopy, EIS, and XRD systematically. Glassy carbon electrode (GCE) was modified with the TMO using 5% Nafion at room conditions. The resultant electrode was used for selective detection of Bisphenol-A (BPA) using cyclic voltammetry (CV). It was observed that the TMO electrode exhibited an excellent sensitivity (3.28μAμM−1cm−2), low detection limit (LOD: 1.2±0.1nM; S/N=3), higher stability, very good repeatability, and reproducibility. In diagnostic exploration, a linear calibration plot was obtained for a wide range of concentration of BPA (LDR: 0.80 to 7.20μM; r2: 0.99). This method represents an efficient way of sensitive sensor development for the detection of toxic and carcinogenic phenolic compounds.
