NOVELTY - Determination of residues of antibiotic chloramphenicol (CAP) in food for synthesizing copper ferrite-graphene oxide material coated on a central electrode of screen-printed electrodes electrode to bind to the CAP residue in the sample to be measured. USE - The method is useful for determination of residues of antibiotic CAP in food for synthesizing copper ferrite-graphene oxide material. ADVANTAGE - The method allows rapid identification of CAP in samples with a detection threshold of 2 M allowing rapid screening and control of foods with CAP residues.
