摘要
介绍了 0 .2 8 %胺菊酯·高效氯氰菊酯气雾剂的气相色谱分析方法。选用 5 %SE - 30 ChromsorbWAW -DMCS(15 0～ 180um)色谱柱 ,以邻苯二甲酸二正辛酯为内标物进行定量分析测定 ,该方法简单、快速、准确、适用。结果表明胺菊酯和高效氯氰菊酯的标准偏差分别为 0 .2 4 %和 0 .11% ;变异系数分别为 0 .94 %和 1.74 % ;平均回收率分别为 99.6 4 %和 99.95 % ;线性回归系数分别为 0 .9999和 0 .9998。
A gas chromatographic method was developed for separation and determination of tetramethrin and bata-cypermethrin in their mixture, by using 5 % SE-30/ChromsorbWAW-DMCS(150～180 um). Di-n-octyl phthalate was employed as internal standard in their quantitative analysis. The method was convenient, rapid and accurate. The results showed that standard deviations were 0.24 % and 0.11 %; coefficient of variations were 0.94 % and 1.74 % ; the average Recoveries were 99.64 % and 99.95 % ; Linear correlatios were 0.9999 and 0.9998。
