【摘要】 采用气相色谱-质谱联用仪(GC-MS)分析了东北某钢铁厂土壤中15种酞酸酯类化合物(PAEs)。结果表明,该方法对15种酞酸酯分离好,平均加标回收率为74.8%~121%,精密度RSD(n=5)在8.3%~13.9%之间,方法检出限为0.01~0.09mg/kg。方法操作简便、准确,具有较好的实用性。更多还原

【Abstract】 A reliable GC-MS method was established for 15 kinds of phthalic acid ester(PAEs) in samples of soil.The result demonstrated that 15 phthalate can be separated complete with the recoveries range of 74.8%～121%,the accuracy RSD(n=5) range of 8.3%～13.9%.The method detection limits were from 0.01 mg/kg to 0.09 mg/kg.The determination method with the advantages of simple operation and accuracy is practical in soil analysis.更多还原
