A simple electrochemical method has been developed for the simultaneous determination of dihydroxybenzene isomers in wastewater samples with poly (glutamic acid) modified electrode (PGA/GCE). PGA/GCE was fabricated by electropolymerization of glutamic acid on a glassy carbon electrode (GCE) through cyclic voltammetry (CV). PGA/GCE showed an excellent electrocatalytic ability towards the oxidation of hydroquinone (HQ) and catechol (CC). With CV and differential pulse votammetric (DPV) measurements, HQ and CC in wastewater samples could be simultaneously analyzed at PGA/GCE. The linear range for HQ and CC were 5 - 100 μM and 2 - 160 μM, with a detection limit of 2.0 μM and 1.0 μM, respectively. Moreover, PGA/GCE exhibited good selectivity and repeatability. The method has a promising application in the monitoring of HQ and CC of wastewater.
