摘要
通过HP-5MS色谱柱对塑胶跑道材料中苯系物进行分离,内标法定量,建立了气相色谱-质谱新方法,用于测定塑胶跑道材料中苯系物含量。实验结果表明:苯、甲苯、乙苯和二甲苯、甲苯二异氰酸酯、六亚甲基二异氰酸酯的回收率分别为95%、94%、103%、98%、92%,精密度均小于3%。表明该方法可以用于塑胶跑道材料中苯系物含量的测定。
The benzene series in plastic track were detected by gas chromatograph-mass spectrometry. HP-5MS chromatographic column was used for the benzene series separation and the internal standard method was used for quantitative analysis. Main results for this study are as follows. The recoveries of benzene, toluene, ethylbenzene and xylene, toluene-2,4-diisocyanate, as well as hexamethylene diisocyanatewere95%, 94%, 103%, 98%, 92%, respectively. The precision of the methods was less than 3%. The method can be used to detect the benzene series contents in plastic track.
