摘　　要：塑胶跑道具有弹性强、耐磨性强、防滑性能优异等优点。塑胶跑道中的粘胶剂及铺设所使用的粘胶材料中均含有一定量的甲苯二异氰酸酯(TDI);TDI是塑胶跑道有毒气体的主要来源,在视觉上呈淡黄色或淡白色,此物质会对人体呼吸通道有很强的刺激性。本实验建立了超声萃取与气相色谱-质谱(GC-MS)联用的方法来检测塑胶跑道中粘胶剂的TDI含量,检测出的加标回收率均达到96.52%~100.62%,中间偏差相差2%,运用3倍的信噪比计算出检测极限为0.148μg/L。The plastic runway has the advantages of strong elasticity,strong wear resistance and excellent skid resistance,but the adhesive in the plastic runway and the adhesive material used in the laying contain a certain amount of TDI,which is the main source of toxic gas in the plastic runway.TDI,visually yellowish or pale white,is highly irritating to the respiratory tract of the human body.In this paper,a method of ultrasonic extraction combined with gas chromatography-mass spectrometry(GC-MS)was established to detect the content of TDI of adhesives in the plastic track.The recoveries of the detected spiked samples range from 96.52%to 100.62%,with a difference of 2%.The detection limit was calculated to be 0.148μg/L by 3-fold signal-to-noise ratio.
