Study on the polyfurfural film modified glassy carbon electrode and its application in polyphenols determination

► We provided a novel polyfurfural film modified glassy carbon electrode. ► EIS characterization suggested polyfurfural film formation conditions. ► The modified electrode can be used for simultaneous determination of hydroquinone, catechol and resorcinol. ► The modified electrode can also be used simultaneous determination of resveratrol and quercetin.
