Abstract
The “game changer” Hydroxychloroquine (HCN) has been regarded as a potential medication and a trial resort for COVID-19 treatment.The effluents containing elevated levels of HCN discharged from human waste and production sites pose considerable concern over aquatic ecosystems. In this regard, we have designed alkali metal tantalates ATaO3 (A= Na and K) based metal oxides synthesized via NADES abetted hydrothermal approach anchored to functionalized carbon nanofiber resulting in an efficient electrocatalyst. Utilizing Thymol-Menthol NADES as a solvent medium marks 100 % atom economy and provides the metal oxides with spectacular characteristics. The effective electrochemical sensing of the HCN was investigated through cyclic voltammetry and electrochemical impedance study by comparing the bare and the fabricated electrodes. Among the fabricated sensors, the excellent conjunction of NaTaO3 and F-CNF with plenty of surface-active sites provides a pronounced rapid charge transfer kinetics response. Furthermore, the comprehensive investigation of NaTaO3/F-CNF electrode benefits from an inclusive concentration range 0.001–141.16 µM, low detection limit 2.1 nM, good reproducibility, and good operational stability. These key factors point to the practical viability of the modified sensor toward the complete assessment of the HCN drug in real-time samples that unveil acceptable recovery results and mark its use in clinical science.
