摘要
应用溶剂解吸-气相色谱法测定制鞋业排放废气中的正己烷,采用活性碳管采集成型车间排气筒中的废气,用二硫化碳解吸,填充柱分离,经FID检测器检测。废气中与正己烷共存的苯、甲苯、二甲苯在该方法下不干扰测定。解吸率高,测定精度高,该法具有准确、快速、灵敏、简便的特点。
The n-hexane was determined by desorption gas chromatography in the waste gas discharged from shoe-making enterprise. The gas that exhausted from the chimney of casting workshop was collected by activated carbon pipe, then desorbed by carbon bisulfide,isolated by packed column and detected by FID-Detecter. With this method the interference of co-existing benzene, toluene and xylene can be eliminated. The method is accurate,quick,sensitive and easy for use.
