| 摘 要： | 经过对样品前处理过程的研究和优化,建立了丙环唑和嘧菌酯的气相色谱分析方法。样品经乙腈水溶液提取分配后,用弗罗里硅土小柱净化,采用气相色谱(μ-ECD)测定。方法中目标物在50~2 000μg·L-1浓度范围内线性良好,相关系数分别为0.999 1和0.999 4。在5,50,200μg·kg-13个添加浓度水平下,平均加标回收率在79.2%~110.9%之间,相对标准偏差不大于15%。该方法可灵敏、简便、快速地测定玉米中丙环唑和嘧菌酯的残留。

| Abstract: | Through studying and optimizing of sample preparation process, an gas chromatography method was developed lor propiconazole and azoxystrobin in cron and soil. The sample were extracted with acetonitril and water, cleaned-up by an magnesiumsilicate solid phase, and analyzed by GC-ECD. The standard calibration curves for two pesticides showed high correlation coefficients over the range of 50-2 000 μg·L^-1, with the correlation coefficients between 0.999 1 and 0.999 4.The average recoveries of two pesticides at the three levels of 5,50 and 200 μg·Lkg^-1 were between 79.2% and 110.9%, with the relative standard deviation （RSD） less than 15%. So, this method could be further applied to detection of propiconazole and azoxystrobin in cron and soil. |
