| 摘要: |
| 采用气相色谱-质谱(GC-MS)联用法测定水中9种邻苯二甲酸酯,GC-MS选择SIM扫描方式。邻苯二甲酸酯的方法检出限为0.67~1.84 g/L,平均加标回收率为63.0%~107%,RSD为2.3%~8.0%。该方法用于检测环境水体中邻苯二甲酸酯类化合物,分离效果好,简便快捷,定量准确,但是,检测实验过程中,无水硫酸钠和溶剂都有可能造成邻苯二甲酸酯分析污染。 |

| Abstract: |
| A method based on the gas chromatography-mass spectrometry was established to determine 9 kinds of phthalate esters.With selected ion monitoring mode,the detection limits,average recoveries and RSD were 0.67~1.84mg/L,63.0%~107% and 2.3%~8.0%,respectively.The proposed method had been applied in the determination of benzene series in water samples with effective separation,easy operation and high accuracy.However,the sodium sulfate and solvent might cause the interference in phthalate and adipate easters determination. |
