| 摘 要： | 建立了卤水中有机物的固相萃取-气相色谱/质谱分析方法。首先用石墨化碳黑柱对盐湖卤水的有机物进行富集,采用气相色谱-质谱(GC-MS)以扫描离子和选择离子检测模式进行检测。回收率标记物在0.1～1 mg/L范围里线性关系良好,相关系数R=0.998 7;其回收率处于74.00%～96.00%之间,相对标准偏差(RSD)为10.9%。最后用优化的方法检测了所富集的有机物。 |
| 关 键 词： | 固相萃取 石墨化碳黑柱 盐湖卤水 气相色谱-质谱 |

| Abstract: | A method was developed for the determination of organic compounds in saline water by solid-phase extraction-gaschromatography-mass spectrometry(SPE-GC-MS).A solid-phase extraction preconcentration system using commercial graphitized carbon black extraction cartridges was developed for the determination of organic compounds in different saline waters in scan ion mode(SCAN)and the selective ion monitoring(SIM)mode by gas chromatography-mass spectrometry.The linearity of the recovery standard was good between ... |
