Simultaneous determination of Pb2+ and Hg2+ at food specimens by a Melamine-based covalent organic framework modified glassy carbon electrode
Food Chemistry(2023)
摘要
•A glassy carbon electrode was modified by a covalent organic framework.•The electrode was used for mercury (II) and lead (II) simultaneous determination.•Modifier interactions with analytes was studied by computational methods.•The developed electrode was successfully applied in various food samples.
