摘要
本文报道了乙从氟草醚除草剂在稻株、稻谷、土壤和田水中的残留分析方法。样品以甲醇提取，活性比炭－硅镁型吸附剂－氧化铝层析柱净化，气谱（ＧＣ／ＥＣＤ）检测。乙氧氟草醚的囊低检出量为１×１０￣（－１２）克，在稻株、稻谷、土壤和田水中的最低检出浓反分别为０．００５、０．０１、０．００５、０．０００１毫克／公斤。空白样品添加标准回收率试验，三档浓度平均回收率为１０１．３％，变异系数为３．６％。
In present paper,the residual analysis rnethod ofoxyfluorfen in rice plant,grain,soil and paddy water was re-ported.Sarnples were extracted with methanol,purified onCharcoal-Florisil-Aluminum oxide colurnn, and finally,detect-ed bv GC-ECD.The lowest detection limit for oxvnuorfen was1×10￣(-12)g,and the lowest detecting concentration in plant,grain,soil and water was 0.005,0.01,0.005,0.000lmg/kg,respectively.On the level of 0.05～1.00mg/kg(0.01～0.10mg/kg for water),the average spiking recovery was101.3%, with a average CV of 3.6%.
