摘要
目的建立了毛细管GC测定双苯氟嗪中二氯甲烷、乙醇、甲基异丁酮3种有机溶剂的残留量。方法采用HP-INNOWax毛细管柱,FID检测器,DMF为溶剂。结果 3种有机溶剂完全分离,在所考察的浓度范围内具有良好的线性,r为0.9999-1.0000,平均加样回收率分别为99.7%,98.7%,98.9%,RSD分别为2.1%,1.9%,2.0%。结论本法快速、灵敏、准确,适用于双苯氟嗪中有机溶剂残留量的测定。
OBJECTIVE To establish a capillary GC method for the determination of residual organic solvents of dichloroethene, ethanol and methylisobutylketone in dipfluzine. METHODS An HP-INNOWax capillary column was used with FID detector and DMF as solvent. RESULTS The organic residuals including dichloroethene, ethanol and methylisobutylketone were separated and determined. There was a good linearity (r=0.999 9-1.000 0). The average recoveries were 99.7%, 98.7%, 98.9%, with RSD of 2.1%, 1.9% and 2.0%, respectively. CONCLUSION The method is rapid, sensitive and accurate. It can be used for the determination of various organic residuals in dipfluzine.
