紫外荧光法测定煤油总硫含量的研究

Study on Determination of Total Sulfur Content in Kerosene by UltravioLet Fluorescene Method

利用氧化紫外荧光法,通过建立标准曲线,测定了煤油样品的总硫含量,检验了方法的精密度和准确度并与微库仑法测定结果进行比较。研究表明,氧化紫外荧光法测定煤油硫含量,标准偏差为2.3%,与微库仑法结果无显著性差异。

Oxidative ultraviolet fluorescene method was used to determine total sulfur content in kerosene through establishing standard curve.The precision and accuracy of the ultraviolet fluorescene method were compared with the microcoulometric method.The results show that relative standard deviation of results determined by the ultraviolet fluorescene method is 2.3%and has not significant difference with that of the microcoulometric method.
