| 摘 要： | 该文利用毛细管气相色谱法测定了三种塑料食品包装材料中邻苯二甲酸二(2-乙基己基)酯(DEHP)的含量.该方法使用RTX-5为色谱柱,邻苯二甲酸二正辛酯(DNOP)为内标,FID为检测器,用内标标准曲线法定量.在优化的条件下,线性范围为0.035～0.560 mg/L,检出限为0.01 mg/L,相对标准偏差为0.14%～0.60%,加标回收率为99.8%～103.2%.

| Abstract: | Di-2-ethylhexylphthalate （DEHP） in plastic food packaging materials was determined by capillary gas chromatography. The separation was performed on RTX-5 capillary column with a FID detector. The internal stand- ard curve method was used for the quantitative estimation with di-n-octylo-phthalate as the internal standard. The linear range was 0.035 - 0. 560 mg/L with a detection limit of 0.01mg/L. The relative standard deviations were from 0.14% to 0. 60% for different concentrations, and the spiked recoveries were 99.8% - 103.2%. |
