摘　　要：鉴于当前国家标准GB 16663中总硫含量分析方法的缺失,采用了紫外荧光法测定醇基液体燃料中的总硫含量。通过考察确定了影响测定结果的最佳试验条件,并建立标准工作曲线来测定总硫含量。验证了方法的精密度和准确度,为国家标准的修订提供了有意义的依据。In view of the lack of analytical methods for total sulfur in national standard GB 16663,the ultraviolet fluorescence method was used to determine the total sulfur in alcohol-based liquid fuels.The optimal experimental conditions affecting the determination results were determined through investigation,and the standard working curve was established to determine the total sulfur content.The precision and accuracy of the method were verified.This study provides a meaningful basis for the revision of the national standard.
