正构烷烃萘芳烃含量的测定

Determination of N-alkane Naphthalene Aromatics Content

为了测定正构烷烃产品中的萘芳烃含量,本研究通过绘制萘标准曲线,确定290 nm波长下的吸收系数,再通过测量特定条件下试样的吸收光谱来确定其含量。此分析方法收率在100%～110%,变异系数为1.96%,通过验证判断,此分析准确、可靠,可用于实际分析。

In order to determine the content of naphthalene aromatics in normal paraffin products, this study determined the absorption coefficient at 290 nm by drawing a naphthalene standard curve, and then determined the content of the sample by measuring the absorption spectrum of the sample under specific conditions. The yield of this analytical method is between 100% and 110%, and the coefficient of variation is 1.96%. This analysis is accurate and reliable and can be used for actual analysis.
