| 摘 要： | 以猪粪中常见且具有较大潜在危害的E1(雌酮)，17α-E2(17α-雌二醇)，17β-E2(17β-雌二醇)和E3(雌三醇)为研究对象，建立了猪粪中这4种典型类固醇雌激素的GC-MS(气相色谱-质谱)分析检测方法.着重优化了样品的前处理方法，包括对超声提取剂、超声提取时间、固相萃取淋洗剂、衍生化温度和时间的优化选择.结果表明:在优化的试验条件下，猪粪中的典型雌激素E1，17α-E2，17β-E2和E3检出限分别为8.0，2.5，5.1和3.3 μg/kg，平均加标回收率在92.3%～137.4%之间.

| Abstract: | Great potential harm from livestock manure is commonly found in estrone(E1),17α-E2(17α-estradiol),17β-E2(17β-estradiol) and E3(estriol).Gas chromatography/mass spectrometry(GC-MS) method was developed for the analysis and quantification of the four typical steroid estrogens in pig manure samples.The pre-treatment method was carefully optimized,including the options for the ultrasonic extraction solvent,extraction time,solid phase extraction eluent,derivatization temperature and time.The results showed that the detection limits for E1,17α-E2,17β-E2 and E3 in pig manure were 8.0,2.5,5.1 and 3.3 μg/kg under the optimal experimental conditions.The average spiked recoveries were in the range of 92.3% to 137.4%. |
