建立了食品包装材料中三（1，3-二氯丙基）磷酸酯、磷酸三氯丙酯2种有机磷酸酯含量测定的气相色谱检测方法。对前处理过程中超声波萃取条件进行优化：选择丙酮为萃取溶剂，用量为20mL，萃取时间为30min。试验结果表明：2种有机磷酸酯的线性范围为0．1～50mg/L，检出限为0．04mg/kg，方法的加标回收率为89．2％～96．2％，相对标准偏差为2．62％～4．78％。
建立瞭食品包裝材料中三（1，3-二氯丙基）燐痠酯、燐痠三氯丙酯2種有機燐痠酯含量測定的氣相色譜檢測方法。對前處理過程中超聲波萃取條件進行優化：選擇丙酮為萃取溶劑，用量為20mL，萃取時間為30min。試驗結果錶明：2種有機燐痠酯的線性範圍為0．1～50mg/L，檢齣限為0．04mg/kg，方法的加標迴收率為89．2％～96．2％，相對標準偏差為2．62％～4．78％。
건립료식품포장재료중삼（1，3-이록병기）린산지、린산삼록병지2충유궤린산지함량측정적기상색보검측방법。대전처리과정중초성파췌취조건진행우화：선택병동위췌취용제，용량위20mL，췌취시간위30min。시험결과표명：2충유궤린산지적선성범위위0．1～50mg/L，검출한위0．04mg/kg，방법적가표회수솔위89．2％～96．2％，상대표준편차위2．62％～4．78％。
An analytical method for determination of organophosphorus triesters ,such as Tris(2-chloropro-pyl)Phosphate(TCPP) and Tris(1,3-dichloro-2-propyl)Phosphate (TDCP) in food packing materials was es-tablished by gas chromatography method .The samples were extracted by supersonic extraction and the optimum conditions of extraction were obtained as the following:acetone used as the extraction solvent , the extraction time was 30min and the solvent volume was 20mL.The linear ranges of 2 kinds of organophosphorus triesters were 0.1~50mg/L,and the detection were 0.04mg/kg.The method recoveries were in the range of 89.2%~96.2%,and the method precisions were 2.62%~4.78%.
