| 摘 要： | 目的建立饮用水中灭草松和2,4-滴的固相萃取高效液相色谱串联质谱测定方法。方法样品经C18固相萃取柱富集浓缩,利用C18色谱柱分离待测物,以甲醇和0.2%甲酸水溶液为流动相等度洗脱,负离子模式下质谱多反应监测(MRM)模式检测,外标法定量。结果灭草松和2,4-滴分别在0.122~298和0.612~1 488 ng/L的范围内线性关系良好,相关系数均大于0.999 0,检出限分别为0.078和0.235 ng/L,定量下限分别为0.261和0.782 ng/L。该方法灭草松的平均回收率为88.8%~103%,RSD9.1%,2,4-滴的平均回收率为92.3%~93.1%,RSD4.1%。结论该方法灵敏度和精密度均较高,回收率和重复性良好,适用于饮用水中灭草松和2,4-滴的测定。
