- Abstract
The development of an efficient, precise, and reliable method for identifying hazardous substances in environmental samples has drawn a lot of attention in the current research environment. The process of electrochemical polymerization produces conducting and non-conducting polymers from electroactive monomers on the electrode surface. By adjusting specific interactions between the functional groups on the polymer and the electrode surface, the electrodes modified by electropolymers can be tuned for a particular usage. Here we present an easy, sensitive, and straightforward method for the electro-polymerization of 4-amino-6-chloro-1,3-benzene disulfonamide on a graphite electrode, which allows for the simultaneous determination of hydroquinone (HQ) and catechol (CC). The electrochemical activity of ACBSA-modified pencil graphite electrode (PGE) towards the analytes in contrary to other reported polymer-based sensors is dramatically enhanced in terms of the concentration range and detection limit. The fabricated sensor has a lower detection value of 3.15 μM for CC and 0.6 μM for HQ. The polymer can act as a versatile medium for the electrochemical determination of catechol and hydroquinone in water samples with distinct oxidation peaks.
