| 摘 要： | 目的建立食品中高氯酸盐的超高效液相色谱-串联质谱(UPLC-MS/MS)的测定方法。方法香辛料调味品用水提取,蔬菜、水果用乙腈-水(1∶1,V/V)提取,肉、禽、蛋、奶和水产品用乙腈-水(2∶1,V/V)提取,C_(18)柱(3 ml,200 mg)净化,以高氯酸根为内标定量,采用UPLC-MS/MS法测定。结果在0.3~20.0μg/L范围内,3种提取溶液中高氯酸盐有良好的线性关系,R~2≥0.999。加标浓度在2.0~50.0μg/kg范围内,内标相对平均回收率为82.6%~108.6%,相对标准偏差(RSD)为1.0%~9.9%。牛奶的定量限为2.0μg/kg,其他食品的定量限为10.0μg/kg。结论本方法简单快捷,定量准确,适用于食品中高氯酸盐的测定。
