介绍了一种同时测定大气粉尘中天然橡胶（NR）和丁苯橡胶（SBR）胎面胶颗粒的方法。颗粒橡胶在740 ℃热解。在居里点热解器中加热5秒钟。用配备双火焰离子化检测器的气相色谱仪分离和检测所得热解物。在几种裂解产物中，异戊二烯和苯乙烯分别被选为NR和SBR的指示化合物。该方法适用于一套大气粉尘样品收集在首尔，韩国的安德森采样器和一些分析结果。
A method for simultaneous determination of natural rubber (NR) and styrene-butadiene rubber (SBR) tire tread particles in atmospheric dust is described. Particulate rubbers are pyrolyzed at 740.degree. C for five seconds in a Curie-point pyrolyzer. The resulting pyrolyzates are separated and detected by a gas chromatograph equipped with dual flame ionization detectors. Among several pyrolysis products, isoprene and styrene are chosen as indicator compounds for NR and SBR, respectively. The method is applied to a suite of atmospheric dust samples collected in Seoul, Korea by an Andersen sampler and some analytical results are presented.
