摘要: 采用HPLC法检测猪肉中5种磺胺类药物残留,在NY5029-2001附录E方法的基础上,探讨了流动相、SPE小柱及洗脱流速对试验的影响。结果表明,使用SB C18柱,流动相为甲醇∶乙腈∶2.2%乙酸水溶液=15∶15∶70时,5种磺胺类药物可得到较好的分离,使用Waters 碱性氧化铝SPE柱及控制洗脱流速可以得到较高的回收率,提高试验准确性。

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
