车用汽油硫含量的测定是促进汽油质量升级,减少环境污染的必备技术手段。本文从车用汽油硫含量测定的意义入手,分析了车用汽油硫含量测定技术,主要包括X射线荧光光谱法、紫外荧光法、氧化微库仑法、气象色谱选择性检测器联用法四种。重点分析采用氧化微库仑法对硫含量进行测定时,车用汽油硫含量测量准确性的影响因素,有效提高测定结果的准确性。
Determination of car gasoline sulfur content is to promote the quality of gasoline upgrade, reduce the necessary technical means of environmental pollution. This paper starts with the significance of the determination of sulfur content in motor gasoline, and analyzes the determination of sulfur content in motor gasoline, including four methods: X-ray fluorescence spectrometry, ultraviolet fluorescence method, oxidized microcoulometry method and meteorological chromatographic selective detector method. Focus on the use of oxidized microcoulomb method for the determination of sulfur content, automotive gasoline sulfur content measurement accuracy of the factors that effectively improve the accuracy of the determination results.
