Electrochemical simultaneously determination of phenol and o-cresol in water based on Zno nanosheets

Abstract

Phenol and o-cresol are two organic contaminants largely produced by many industries and could potentially harmful people and environment. In this study, we proposed an electrochemical approach that could simultaneously determination of phenol and o-cresol. This method contained a commercial electrode surface modification process that deposition of ZnO nanosheets on the screen printed electrode (SPE). The fabricated sensor exhibited an outstanding electrocatalytic performances toward electro-oxidation of phenol and o-cresol. After optimization of the detection condition, the detection range and detection limit of the sensor were determined. Moreover, the proposed sensor also successfully applied for detecting phenol and o-cresol on the real wastewater.
