| 摘 要： | 对直接进样、二硫化碳萃取和活性碳纤维固相微萃取 (ACF SPME)分别与气相 质谱联用测定水中的苯系物的方法进行了比较研究。对 3种方法的线性、重复性、最小检出限等进行了试验测定。测定结果表明 ,固相微萃取在灵敏度方面优于其他方法 ,但在重复性方面还有待提高。利用固相微萃取方法进行了实际废水样的检测及回收率试验 ,结果令人较为满意。

| Abstract: | The methods of direct injection, carbon disulfide extraction and activated carbon fiber solid phase microextraction/GC MS, usually used in the determination of BTEX in water matrix, are compared and discussed. Experimental data of linearity, precision and limit of detection illustrate that the last one is better than the two other methods This method was tested by the practical sample experiments and expected to be a simple and sensitive new method for the analysis of BTEX in water |
