电子电器产品中三（2-氯乙基）磷酸酯测定

摘要

使用丙酮-甲醇混合溶液,对电子电器产品中的三(2-氯乙基)磷酸酯进行超声萃取,用气相色谱-质谱联用仪进行定性/定量测定,并进行了检出限、回收率、精密度等试验。试验结果表明：检出限为0.72 mg/kg,回收率85.2%~110.4%,精密度为1.76%~3.26%,相对标准偏差RSD(n=6)小于5%。方法简单高效,适用范围广,能够很好的适用于电子电器产品中的三(2-氯乙基)磷酸酯的检测。%A qualitative and quantitative analysis method for the determination of tris (2-chloroethyl) phosphate in electrical and electronic products was carried out by SCAN/SIM mode with GC-MS after being extracted with acetone-methanol by ultra-sonic instrument. The method was simple and efficient, wide application, the detection limit was 0. 72 mg/kg, recoveries was 85. 2% ~110. 4%, and the precision was 1. 76% ~3. 26%. The method was successfully applied to the determination of tris (2-chloroethyl) phosphatein in electrical and electronic products.
