| 中文摘要: |
| 采用乙酸乙酯-正己烷混合溶剂（体积比为2〖JP20〗∶〖JP〗1）对饮用水源地水中阿特拉津、林丹、邻苯二甲酸二正丁酯（DBP）、邻苯二甲酸二（2-乙基己基）酯(DEHP)和滴滴涕（含4种）等8种半挥发性有机物进行1次水样萃取，用气质联用法同时测定。试验表明，方法在25.0μg/L～500μg/L范围内线性良好；检出限在0.006 μg/L～0.028 μg/L之间；空白水样3个质量浓度水平的加标回收率为87.6%～109%，平行测定6次的RSD<5.1%；测定集中式生活饮用水源地的实际水样，未检出目标化合物，加标回收率为98.6%～109%。 |
| 英文摘要: |
| The mixed solvent of ethyl acetate and hexane（V〖JP20〗∶〖JP〗V=2〖JP20〗∶〖JP〗1） was used as extraction solvent to determine three kinds of semivolatile organic compounds in water.The compounds were impactful separated from each other through DB 1 capillary column (30 m×0.25 mm ×0.25 μm) and then determined by GC MS.The linearity ranged from 25.0 μg/L to 500 μg/L.The detection limits ranged from 0.006 μg/L to 0.028 μg/L.The relative bias of replicate measurements of standard solution were less than 5.1%.The average recoveries were within the range of 87.6 %～109 %. |
