The application of penicillin and cephalosporin intermediate 7-ACA in animal feeding is very common, and the safety issues caused by the residues cannot be ignored. In order to explore the test conditions for the determination of penicillin and 7-ACA content by iodometry, experimental research is carried out. The experimental results show that the determination of penicillin and 7-ACA content by the iodometry has the advantages of simple and fast operation, accurate measurement results and good precision; under the optimal test condition, the recovery rate of penicillin and 7-ACA is more than 90%.
