Abstract
Abstract Owing to their widespread and persistent usage, 1-chloro-4-nitrobenzene (CNB) and N-(4-hydroxyphenyl) acetamide (ACT) are two environmental substances that have raised several concerns in the environment recently by posing significant threat to human life and the general environment. Herein, we designed a highly sensitive electrochemical sensing platform for the simultaneous detection of CNB and ACT by doping the already super-conductive carbon black (CB) with nitrogen heteroatoms to attain a nitrogen-doped CB (NCB) nanocomposite. The proposed method exhibited excellent electrochemical activities towards the oxidation of CNB and ACT by producing high peak currents. Also, the oxidation peak potentials of these two compounds were wide enough to make clear distinctions between them. Based on the optimal experimental parameters, the linear determination ranges for both targets by the proposal are 0.05–50.0 µM, and detection limits of 0.007 µM and 0.008 µM were recorded for CNB and ACT respectively. In addition, the sensing platform showed good reproducibility, excellent stability, the ability to withstand possible interference from familiar compounds and the potential to detect CNB and ACT in routine real sample analysis.
