摘要

A simple, convenient and highly sensitive sensor for ascorbic acid (AA) detection is presented. Thesensor was prepared based on graphene oxide (GO) and ionic liquid (IL) 1-butyl-3-methylimidazoliumhexafluorophosphate (BMIMPF6) nanocomposites. Scanning electron microscopy and Fourier transforminfrared spectroscopy were used to study the morphology and functionalization of the sensing materials.The electrochemical detection of ascorbic acid was studied by differential pulse voltammetry, utilisinga GO-IL modified glassy carbon electrode (GCE) in a linear response range from 0.01 mM to 4.0 mM,which exhibited a relatively low detection limit of 3.33 μM ( S / N = 3 ). In addition, the GO-ILnanocomposite exhibited appreciable stability, reproducibility and selectivity. The electrochemicalsensor can be used for the determination of ascorbic acid in actual drugs.
