A method for the determination of residues of quinoxaline-2-carboxylic acid (QCA), the major metabolite of carbadox, in pig kidney has been developed. Tissue samples were subjected to alkaline hydrolysis, liquid-liquid extractions, ion-exchange chromatography and further extraction to concentrate the analyte
