Improvement of the Determination Method of Benzene, Toluene,Ethylbenzene and Xylene(BTEX) in Water Using ActivatedCarbon Fiber Solid-Phase Microextraction/GasChromatography-Mass Spectrometry(GC-MS)
活性碳纤维固相微萃取/气相-质谱联用测定水中苯系物

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
