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0.001~0.002mg/mL,均能达到国家标准方法的测定要求。
In this paper, headspace-automatic capillary injections were used to determine the content of benzene (including benzene and its homologues toluene, ethylbenzene, m-xylene, p-xylene and o-xylene) in natural water and analyzed by gas chromatography Water benzene compounds, the results show that the headspace GC method for the determination of benzene in natural water method is feasible, practical, precision and high accuracy, the detection limit of 0.001 ~ 0.002mg / mL, can reach the national The standard method of measurement requirements.
