Abstract
An external standard method for determination of illegal additives in gasoline by heart-cut gas chromatography is developed in this paper to rapidly analyze methylal and aniline compounds. Results show that, the linear relation of seven target compounds is good in the range of 0~30% (V/V). The recoveries of the additives are in the range of 95.37%~103.10%. The relative standard deviations of six repeated determinations are less than 2.00%. The study shows that the detection limit of methylal is 0.00134%, and the detection limits of aniline compounds are less than 0.002%.关键词
