摘要
建立了欧盟2007/19/EC指令中限制的对与食品接触的塑料材料中七种邻苯二甲酸酯迁移量的检测方法。样品采用食品模拟物浸泡后,取浸泡液用正乙烷进行液-液萃取,气相色谱仪/质谱联用仪(GC/MS)采用选择离子方式(SIM)检测,内标法定量。DBP、BBP、DEHP、nDnOP、DIDP、DINP、DAP检出限各为0.20,0.50,0.20,0.50,2.0,2.0,0.003mg/kg。七种邻苯二甲酸酯在加标回收水平0.3(3,0.01)-50(500,5/3)mg/kg范围内,回收率为81.3-116%。
Established determination methods of seven phthalates migration in foodstuff plastic materials by the restriction of 2007/19/EC EU Directive.The aqueous simulant test samples are extracted with n-hexaneand.The resultant solution are analysed by gas chromatography/mass spectrometry and phthalates are determinated by internal standard method.The detection limit of DBP,BBP,DEHP,nDnOP,DIDP,DINP,DAP seperately was 0.20,0.50,0.20,0.50,2.0,2.0,0.003 mg/kg.The recovery at the level of 0.3（3,0.01）-50（500,5/3）mg/kg of determination limit 81.3-116%.
