摘　　要：A simple and green method was introduced to fabricate the electrochemical sensor based on the electrochemically reduced graphene oxide（ERGO） modified electrode. It was found that the ERGO modified electrode exhibited an excellent catalytic activity toward the oxidation of dihydroxybenzenes isomers. Under the optimum conditions, in the simultaneous determination of the dihydroxybenzene isomers, the currents were linear with the concentrations of the isomers from 5 to 550 μmol/L for hydroquinone（HQ）, from 6 to 400 μmol/L for catechol（CT） and from 5 to 350 μmol/L for resorcinol（RS）, respectively. In addition, the proposed sensor has good stability and reproducibility. The developed method has been applied to the simultaneous determination of dihydroxybenzene isomers in real samples with a satisfactory recovery from 98% to 103%.A simple and green method was introduced to fabricate the electrochemical sensor based on the electrochemically reduced graphene oxide（ERGO） modified electrode.
