摘　　要：通过添加回收率试验,借助气相色谱分析技术,建立了乙氧氟草醚在稻田环境中的残留分析与检测方法。该方法采用甲醇提取水稻土壤样品的乙氧氟草醚,采用乙酸乙酯提取水稻植株、谷壳和糙米样品中的乙氧氟草醚,均用石油醚纯化,GC-ECD进行检测;结果表明该检测方法准确度高,重现性好,操作简便,适用于稻田水、稻田土壤、水稻植株、谷壳和糙米样品中的乙氧氟草醚残留分析。The fortified recoveries experiment and the gas chromatography （GC） were used to establish a method for determining and analyzing oxyfluorfen residue in paddy field. This method use ethyl acetate to extract oxyfluoffen from samples of rice plant, rice hull and brown rice and use methanol to extract oxyfluorfen from sample of rice soil, then the extracted oxyfluorfen will be purified by petroleum ether, and then be detected using GC-ECD. The results showed that this detection method has characters of high accurate, good repeatability and easy operation, so it suits for analyzing the oxyfluorfen residue in water and soil of paddy field, rice plant, rice hull and brown rice.
