| 摘 要： | 考察能量色散X射线荧光光谱法与微库仑法在出口汽油硫含量项目检验中测定结果的差异；采用能量色散X射线荧光光谱法与氧化微库仑法对部分出口汽油中的硫含量进行了检验，并对测定结果进行了对比与分析；两种方法都有较高的精密度，光谱法所测结果普遍大干库仑法所测的对应结果；样品中硫含量值越小，两方法所测定硫含量间的相对偏差值越大。 |
| 关 键 词： | 能量色散X射线荧光光谱 微库仑 出口汽油 硫含量 |

| Abstract: | Sulfur content in export gasoline has been determined by energy dispersive X-ray fluorescence spectrometry and oxidative microcoulometry.The differences between the two methods are compared and analyzed.It is found that the precisions for both the spectrometry and microcoulometry are good.Results measured by spectrometry are generally larger than that obtained by microcoulometry.The lower the sulfur content in samples is,the bigger the differences are for the relative deviation value on the measuring result... |
| Keywords: | Energy dispersive X-ray fluorescence spectrometry Microcoulometry Export gasoline Sulfur content |
