丙烯腈是高分子化学工业的重要原料之一,但它是对人体有害的物质,又容易挥发、扩散于生产或使用它的现场空气中。为了保证工人的身体健康。要求测定现场空气中丙烯腈的浓度。 已见报道的测定空气中丙烯腈浓度的方法有检测管法、纳氏试剂法、硫醇试剂法、酸碱滴定法、极谱法、色谱法和萤光照射法等。在萤光照射法中可采 Acrylonitrile is one of the important raw materials in the polymer chemical industry. However, it is a harmful substance to the human body and is easily volatilized and diffused in the air of the production or use of it. In order to ensure the health of workers. Requires determination of acrylonitrile concentration in the air at the scene. Has been reported to determine the concentration of acrylonitrile in the air by the detection tube method, Nessler reagent, mercaptan reagents, acid-base titration, polarography, chromatography and fluorescence irradiation and so on. In fluorescent irradiation method can be taken
