Simultaneous electrochemical sensing of heavy metal ions (Zn2+, Cd2+, Pb2+, and Hg2+) in food samples using a covalent organic framework/carbon black modified glassy carbon electrode

•The COF was synthesized by a mild and facile modification method.•CB-COF/GCE was used to detect Zn2+, Cd2+, Pb2+, and Hg2+ for the first time.•The modified GCE shows satisfactory performance in the analysis of ions by DPASV.•The sensor was employed to determine Zn2+, Cd2+, Pb2+, and Hg2+ in food sa...
