摘要： 采用溶胶-凝胶包埋技术制备了耐高温固相微萃取头(SPME),用该萃取头与气相色谱-热离子化检测器联用对红葡萄酒中的12种有机磷农药残留进行了测定。实验中对搅拌速度、萃取时间、盐浓度等条件进行了优化。结果表明，在样品用量25 mL，搅拌速度1250 r/min，盐浓度 150 g/L，萃取时间30 min的条件下，绝大多数组分峰面积的相对标准偏差（RSD）在5%以下，各种有机磷农药的检测限为5 ng/L到0.38 μg/L。

Abstract: A method for the determination of 12 organophosphorus pesticide residues (OPs) in red wine by fiber solid phase microextraction (SPME) coupled with gas chromatography (GC) was developed and validated. The SPME phase was prepared by sol-gel technology of physical incorporation. The extraction conditions were optimized with the results of stirring rate of 1250 r/min, NaCl mass concentration of 150 g/L, and extraction time of 30 min. With the sample volume of 25 mL, the relative standard deviations (RSD) of peak areas for most of OPs were below 5%, and the detection limits of OPs were in the range of 5 ng/L-0.38 μg/L. It can be seen from the results that this method has the potential to analyze OPs in other beverages and soft drinking materials.
