摘　　要：介绍了一种测定轻质油品中测定痕量硫的仪器分析方法。使用ANTEK9000元素分析仪,根据紫外荧光法,微量注射器手动进样的方式测量石脑油馏分的痕量硫。结果表明,该方法检测限低,测定结果的相对标准偏差不大于5%,相对误差在±10%以内,具有操作简捷、准确度高、重复性好以及高选择性等优点,适用于痕量硫的测定。A method of determination of trace sulfur in the light oil sample was introduced. The ANTEK9000 element analysis equipment was used to determine the trace sulfur of naphtha distillate by putting the sample with micro injector manually. The result showed that this method could determine the lower nitrogen content, the relative standard deviation was less than 5% , and the relative error was less than 10%. The method can be applied to determination of trace sulfur in light oil sample because of its simple operation, accuracy, repeatability and high selectivity.
