【摘要】 文章采用顶空-自动、毛细管柱进样对天然水中苯系物(包括苯及其同系物甲苯、乙苯、间二甲苯、对二甲苯和邻二甲苯)进行了测定,通过气相色谱法分析水中苯系物,结果表明用顶空法气相色谱分析测定天然水中苯系物方法是可行的,实用性强,精密度准确度高,检出限在0.001~0.002 mg/mL,均能达到国家标准方法的测定要求。更多还原

【Abstract】 In the paper,determine volatile benzene series compound(including benzene and its homologues toluene,ethylbenzene,xylene,p-xylene and o-xylene) in nature water adopts headspace-auto,capillary column injection,volatile benzene series compound in nature water analysis by gas chromatography,the result is that the method of headspace-gas chromatography sophistication,accurate degree is high,checking a limit in the 0.001~0.002 mg/mL,can reach the national standard methods of determination of requirements.更多还原
