二硝基甲苯（ＤＮＴ）对人体有一定毒性，在车间空气中常以蒸气状态存在。我们研究了用气相色谱测定ＤＮＴ的方法，结果符合《车间空气中有毒物质监测研究规范》［１］。现场应用和验证实验表明，该法可以用于车间空气中ＤＮＴ的检测。一、原理用苯采集ＤＮＴ蒸气，经ＯＶ...
Dinitrotoluene (DNT) on the human body has a certain toxicity, often exist in the workshop in the vapor state of the air. We studied the method for the determination of DNT by gas chromatography and the results were in line with the “Study on the Monitoring of Toxic Substances in the Air” [1]. Field application and verification experiments show that this method can be used to detect DNT in the workshop air. First, the principle of benzene with DNT steam collection, the OV ...
