摘要
目的建立饮料中10种防腐剂同时快速测定的毛细管气相色谱法。方法样品经乙酸乙酯萃取,FFAP毛细管色谱柱分离、FID检测器检测。结果方法线性范围宽,相关系数为0.9986～1.000,回收率为84.5%～113%,相对标准偏差为1.59%～10.32%,方法检出限为0.26～3.2mg/L。结论该法简便、高效、经济、环境友好,适于饮料中10种防腐剂同时快速测定。
Objective To establish a method for simultaneous determination of ten preservatives in beverage by gas chromatography. Methods The analytes in beverage were extracted by ethyl acetate,and then were separated with FFAP capillary column and detected with FID detector. Results Linear ranges of the method were wide with correlation coefficients varying from 0. 9986- 1. 000. Recoveries and relative standard deviations （RSDs）were in the range of 84.5 % - 113 % and 1.59 % - 10.32 % respectively. The limits of detection were in the range of 0.26 -3.2mg/L. Conclusion The method is simple,efficient,cheap,eco-friendly and is suitable for simultaneous deter- mination of 10 preservatives in beverage.
