Abstract: Five sulfonamides residues in pork were determined by HPLC. The influences of mobile phase, SPE column and elution rate on the experiment were discussed on the basis of Appendix E, NY5029-2001. Five sulfonamides residues could be separated efficiently when the proportion of methanol to acetonitrile to 2.2% acetic acid solution was 15∶15∶70 with SB C18 column. Considerable recovery and experimental accuracy could be obtained when the Waters alumina B SPE column was employed and the elution rate was controlled.

Key words: sulfonamides residues; HPLC; solid-phase extraction; recovery
