Flexible Carbon Electrodes for Electrochemical Detection of Bisphenol-A, Hydroquinone and Catechol in Water Samples

摘要: The detection of pollutant traces in the public water supply and aquifers is essential for safety population. In this article, we demonstrate that a simple electrochemical procedure acidic solution can be employed enhancing sensitivity flexible screen-printed carbon electrodes (SPEs) to detect bisphenol-A (BPA), hydroquinone, catechol, simultaneously. SPEs were pretreated electrochemically H2SO4 solution, which did not affect their morphology, yielding high current signals with well separated oxidation peaks. values 0.28, 0.230, 0.056 µA L µmol−1 limits 0.12, 0.82, 0.95 µmol L−1 BPA, respectively. sensors reproducible selective detecting BPA plastic cups, adequate specificity affected by interferents from samples. simple, inexpensive, SPE may thus used emerging pollutants monitor quality.
