| Abstract: | A quantitative GC-MS chromatography method had been developed for the determination of BHT and BHA in the EVA material.BHT and BHA were extracted by hexane,filtering 0.45 μm film,then determined by GC-MS.The calibration curve for BHT and BHA were in good linearity within the concentration range of 0.1～10 mg/L.The average recovery of six spiked concentmtion levels for BHT and BHA were 98.00%～105.00%、94.67%～104.50%,respectively,and its corresponding coefficient of variation(CV) were 0.60%～3.41%,1.71%～3.45%. |
