The presence of sulfonamide (SA) residues in foods is largely due to the raising of animals with sulfonamide antibiotics added or polluted feedstuff. Because of interference from the matrices, the commonly used immunoassay or chromatographic method is not suitable for the analysis of multi-SAs in fe...
