摘要
采用能量色散X荧光光谱法ASTM D 4294作为硫含量测试方法时,受基体效应影响,甲基叔丁基醚、C7-C8、重整汽油对低硫车用汽油的硫含量测定有较大的正偏差。针对硫含量的不同,建议在测试硫含量的北京市地方标准中增加SH/T 0689、SH/T 0742、GB/T 11140,仲裁分析方法改为电量法SH/T 0253。
When EDXRF （ASTM D 4294） is applied to test sulfur content, the determination result of sulfur content for low sulfur automobile gasoline will be higher than reality in the case of gasoline containing MTBE, C7/C8 and reforming gasoline because of influence of matrix effect. According to different sulfur content, suggestions are put forward that SH/T 0689, SH/T 0742 and GB/T 11140 should be added in Beijing municipal local standard for testing sulfur content and arbitration analytic method should use SH/T 0253.
