Direct electrochemical detection of Cu(Ⅱ) ions in juice and tea beverage samples using MWCNTs-BMIMPF6-Nafion modified GCE electrodes

•The GCE sensor based on MWCNTs-BMIMPF6-Nafion detected Cu (Ⅱ) ions.•Nafion can significantly improve the easy falling of the modification layer.•The fabricated sensor has excellent anti-interference and stability.•The fabricated sensor determined Cu (Ⅱ) ions in actual food samples. Due to a small a...
