Abstract
? 2022 Elsevier B.V.Nitrophenols (NPs) extensively used in the manufacture of pesticides, dyes, and pharmaceuticals are categorized as anthropogenic, lethal, and refractory compounds that require massive effects ardent to mitigate the devastating influences on the living environment. A novel, simple and cost-effective tactic to create a sensing platform with excellent electrochemical performance for rapid detection of 3-nitrophenol (3-NP) is necessary for human health and the environment. An electrochemical sensor constructed through a glassy carbon electrode modified by ZnS nanoparticles doped on functionalized CNF coated with PDA had been developed for the detection of 3-NP. The modification of the electrode gives excellent electrocatalytic action and virtuous selectivity towards the reduction of 3-nitrophenol due to its exceptional adsorptive ability, hefty active surface area, and electrical conductivity contributed by the synergism followed by ZnS and PDA@f-CNF. Under optimal experimental conditions, this newly fabricated sensor exhibits good linearity towards 3-NP concentration with a lower detection limit. Moreover, the ZnS/PDA@f-CNF sensor showed good repeatability, reproducibility, and stability. Further, effectual recognition of 3-nitrophenol in urine samples additionally benefits the real time monitoring and practicability of the proposed sensor.
