Sulfadimidine (SDD) was detected in pork imported from Mexico by HPLC with gradient elution system. UV spectrum of the peak was measured and confirmed by photodiode array detector, moreover identified by GC/MS after methylation with diazomethane. Content of SDD in the sample was 0.1 ppm and detection limit of SDD by the proposed method was 0.02 ppm. Application of this method to CLP, SMR, SMM, SDM and SQX was studied, and satisfactory results were obtained.
采用高效液相色谱梯度洗脱系统在从墨西哥进口的猪肉中检测到了磺胺二甲嘧啶（SDD）。用光电二极管阵列检测器测定并确认了该峰的紫外光谱，此外，在用重氮甲烷甲基化后通过气相色谱/质谱进行了鉴定。样品中SDD的含量为0.1 ppm，所提出方法对SDD的检测限为0.02 ppm。研究了该方法在氯丙嗪、磺胺间甲氧嘧啶、磺胺甲噁唑、磺胺嘧啶和磺胺喹噁啉上的应用，并获得了满意的结果。
