摘要
介绍了紫外分光光度法测定芳烃含量，在等吸光点２１２ｎｍ波长处，以间二甲苯为标准物，不经分离，直接测定。实验表明，该法的灵敏度和选择性优于其它方法，并用于石油产品中芳烃含量的测定，结果令人满意。
Determination of aromatics by ultroviolet spectrometry is introduced in this paper. It is directly determinated, without separation and with m-xylene as standard sample at 212 nm isoabsorptive point. The experiment shows that the sensitivity and selectivity of this method are better than others and it is applied to the determination of aromatics in petrochemical products with satisfied results.
