摘要：

A simple and highly selective electrochemical method for the determination of catechol (CC) and hydroquinone (HQ) was developed on carbon paste electrode modified with electropolymerized thin films of benzoguanamine by using cyclic voltammetry. The effects of pH, scan rate, and concentration were carried out electrochemically. The proposed sensor exhibit adsorption controlled process and good limit of detection for CC (2.55 mu M) and HQ (3.84 mu M) were found. The interference study demonstrates the modified electrode exhibits good selectivity and sensitivity. The analytical performance of this modified electrode has been evaluated for detection of CC and HQ in tap water sample as real sample. (C) 2019 Elsevier B.V. All rights reserved.
