乙烯、丙烯,丁烯、丁二烯简称“四烯”,为不饱和脂肪烃,它们在大气中经光化学反应可生成二次污染物。我国目前尚无乙烯和丙烯的车间空气浓度卫生标准及测定方法。为此,我们用501键合硅胶担体测定,报告如下。1 材料与方法1.1 仪器 SP-3420 GC FID 鉴定器; Ethylene, propylene, butylene, butadiene, referred to as “tetraene” for unsaturated aliphatic hydrocarbons, which in the atmosphere by photochemical reactions can generate secondary pollutants. At present, there is no hygienic standard and measurement method for the workshop air concentration of ethylene and propylene in our country. To this end, we use 501 bonded silica gel assay, the report is as follows. 1 Materials and Methods 1.1 Instrument SP-3420 GC FID detector;
