Sensitive electrochemical determination of luteolin in peanut hulls using multi-walled carbon nanotubes modified electrode

► The electrochemical behaviours of luteolin was investigated at MWNTs modified glassy carbon electrode (MWNTs/GCE) ► The detection limit of 6.0 × 10−11 M is achieved based on MWNTs/GCE, which is much lower than that reported in literature. ► The modified GCE have a good stability and repeatability for the detection of luteolin. ► The analytical performance of this sensor has been evaluated for detection of luteolin in peanut hulls as a real sample.
