| Abstract: | The 5-tert-butyl-2,4,5-trinitro-m-xylene(musk xylene) was extracted ultrasonically with toluene.Anhydrous sodium sulfate was added to remove moisture,and then suspended matter was precipitated by centrifugation.The upper clear liquid was purified by Alumina neutral SPE.The external standard method was employed for quantitative analysis with GC-MS.The detection limits(10 S/N) was 0.5 mg/kg.Values of recovery found by standard addition method were in the range of 84.3%-112.3% with the value of RSD's(n=7) less... |
