摘要
用SE-30毛细管柱、160~300℃程序升温、以邻苯二甲酸二环已酯为内标物,气相色谱法同时测定家用气雾杀虫剂中有效成分胺菊酯、氯菊酯的含量。胺菊酯、氯菊酯的平均回收率分别为94.0%、95.4%,相对标准偏差分别为2.23%、6.73%。
Determination of tetramethrin and permethrin in household spray insecticide simultaneity by GC were studied. SE -30 column(30 m ×0.25 mm i. d. , 0.25 μm) was selected, the temperature of column was from 160℃ (hold 2.5 min) to 300℃ (hold 10 min) at the rate of 25℃/min. The linear equation was A = 4. 0224c -0.039 8 and r = 0. 9991 for tetramethrin, A = 6. 5302c - 0.087 3 and r = 0. 997 7 for permethrin. The recoveries were 94.0% for tetramethrin, 95.4% for permethrin. The relative standard deviations were 2.23 % for tetramethrin and 6.73 % for permethrin( n = 6).
