摘要:

建立测定鸡肉、鸡肝和猪肝中溴螨酯残留量的气相色谱- 质谱方法。样品用环己烷- 乙酸乙酯(1:1,V/V)均质提取,提取液浓缩定容后,用凝胶渗透色谱净化,供气相色谱- 质谱仪检测,外标法定量。方法检出限为5μg/kg。鸡肉中的溴螨酯添加水平是5、10、50μg/kg 时,回收率为69.4%~104.6%,相对标准偏差为9.3%~11.9%;鸡肝中的溴螨酯添加水平是5、10、50μg/kg 时,回收率为74.4%~104.5%,相对标准偏差为8.3%~10.8%;猪肝中的溴螨酯添加水平是5、10、50μg/kg 时,回收率为74.6%~103.8%,相对标准偏差为9.6%~11.1%。

Abstract:

A gas chromatograph-mass spectrometric (GC-MS) method was proposed for the determination of bromopropylate residue in chicken meat and liver and pork live. The method was based on the sequential procedure consisting of homogenization for extraction with a mixture composed of cyclohexane and acetic ester (1:1), condensation, constant volume dilution, cleanup by gel permeation chromatography (GPC), GC-MS detection and quantification by the external standard method. The detection limit of the method was 5μg/kg. Spike recoveries for bromopropylate at the levels of 5, 10 μg/kg and 50μg/kg and relative standard deviations were 69.4%-104.6% and 9.3 %-11.9% in chicken meat, 74.4%-104.5% and 8.3%-10.8% in chicken liver and 74.6%-103.8% and 9.6%-11.1% in pork liver.

Key words: bromopropylate, chicken meat, chicken liver, pork liver, gel permeation chromatography, GC-MS
