MnO2 Nanorods Modified Screen Printed Electrode as a Novel Voltammetric Sensor for Specific Detection of Bisphenol A

Bisphenol A (BPA) is an effective endocrine-disrupting compound (EDC) that causes adverse effects on human health and environment. This study reported a novel bisphenol A sensor via MnO2 nanorods modified screen printed electrode. The prepared MnO2/SPE presented fast response, high sensitivity and low background current. Differential pulse voltammetry (DPV) was used as an analytical method for the quantitative determination of bisphenol A, and the fabricated electrochemical sensor exhibits a linear response to bisphenol A in the range of 1.0–300.0 μM with the limit of detection (LOD) of 0.5 μM at a signal-to-noise ratio of 3. The prepared MnO2/SPE has been successfully used for detecting bisphenol A in water samples.
