【摘要】 采用高效液相色谱法,流动相为乙腈+水(78+22),使用Hypersil C18不锈钢柱在235nm波长下同时测定乙草胺和乙氧氟草醚。该方法的标准偏差为0.0019%和0.0017%,变异系数为0.81%和1.06%,回收率分别为99.83%～101.68%和97.27%～100.49%。更多还原

【Abstract】 The quantitative determination of acetochlor and oxyfluorfen by HPLC with Hypersil C18 column at 235nm was described.The mobile phase was acetonitrile+water(78+22).The results showed that the standard deviation was 0.0019% and 0.0017%,the coefficient of variation was 0.81% and 1.06%,and the recovery was 99.83%～101.68% and 97.27%～100.49%.更多还原
