便携式气相色谱-质谱法测定空气中的苯系物

Determination of Benzene and Its Analogues in the Air via Portable GC-MS

苯系物是大气环境中最常见的化合物之一。研究表明,室内环境污染造成的儿童健康问题与苯系物密切相关。而且,近年来苯系物污染事故呈上升趋势。因此,如何准确实施苯系物的现场应急监测成为了妥善处理和处置污染事故的关键。本论文建立了一套标准的苯系物测定方法,顺利获得了多种苯系物的标准图谱,确定了各苯系化合物的标准曲线,实现了苯系物的快速、准确、现场测试。

Benzene and its analogues are common organic pollutants in the air. It was shown that children＇s health problems caused by indoor environmental pollution are closely related to benzene and its analogues. MeanwhiIe, benzene-based pollution accidents have been shown an upward trend in recent years. Hence, the on-site monitoring of benzene becomes a key technology for the emergency response of the pollution accidents. This study established a standard method for the determination of benzene and its analogues in the air via portable GC-MS. The stand chromatogram and standard curve of benzene and its analogues were obtained. This study achieved the rapid, accurate and on-site testing of benzene and its analogues.
