| 摘 要： | 建立了气相色谱(GC-NPD)检测敌敌畏在水稻中残留量的方法。在优化样品前处理方法的基础上,选用DB-35(30m×0.32mm×0.25μm)毛细管色谱柱测定水稻植株、糙米、稻壳、土壤及田水样品中敌敌畏的含量。结果表明,在0.01~1.0mg/kg添加水平范围内,敌敌畏的平均添加回收率为82.2%~106.8%,相对标准偏差(RSD)为0.25%~3.67%,5%(n=5)。该方法操作简便,杂质干扰少,灵敏度、准确度高。

| Abstract: | A method for determining DDVP residue in plant, coarse grain, rice husk, petty soil and water was established based on gas chromatography with nitrogen phosphorus detector （GC-NPD）. After optimizing the sample preparation method, A DB-35 （30m×0.32mm×0.25μm） capillary column was used to determinethe content ofdichlorvos in samples. Results showed that between 0.01-1.0mg/kg spiked levels of dichlorvos, averagerecoveries reached 82.2%-106.8% and the relative standard deviation （RSD） was 0.25%-3.67% which wasless than 5% （n=5）. This method showed simple and rapid characteristic with less impurities interference and high sensitivity and accuracy. |
