Determination of Aromatics in Petroleum Products by Ultroviolet Spectrometry |
| |
| Abstract: | 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. |
