摘要
乙莠悬浮剂由乙草胺和莠去津两种除草剂复配加工而成.本文选择5%OV-17为固定液邻苯二甲酸二戊酯为内标物,用气相色谱法在同一条件下同时测定出两种除草剂的有效含量.乙苯胺和莠去津的平均回收率分别为100.01%和100.05%,标准偏差分别为0.041%和0.036%.
A suspension concentrate mixture of acetochlor and atrazine was analyzed by GC with 5%OV-17 as stationary phase.The method shows that the content of each active ingredient was determined in the same condition,The average recorery amd standard deviation of atrazine and acetochlor were 100.05%,100.01%and 0.036%,0.041%respectively.
