摘　　要：对使用过的SPE柱进行正己烷除杂、干燥等前处理,并将其用于白酒样品的提取和净化。结果表明,该方法具有较高的准确性和精密度;通过加标回收试验,表明该方法具有较好的回收效果。此外,还研究了SPE活化方法对萃取柱性能的影响,发现经过活化处理后的萃取柱能够更好地吸附白酒中的EC,具有更高的灵敏度和选择性。The used SPE was pretreated with n-hexane and drying,and then it was used in the extraction and purification of Baijiu samples.The results showed that the method had high precision and accuracy.Spiked recovery tests showed that the method had good recovery effect.In addition,the effect of the SPE activation method on its performance was studied.It was found that the activated column could better absorb the EC in Baijiu,and had higher sensitivity and selectivity.
