A rapid method for the determination of aromatics in mineral spirits was established by using dual wavelength UV spectroscopy. The conditions for the optimization of mathematical models for the determination of monocyclic and polycyclic aromatic hydrocarbons in solvent oil were studied. The results showed that the correlation coefficients between the chemical value (also known as true value) and the dual-wavelength UV prediction value of the sample set were: monocyclic aromatic hydrocarbon R = 0.9628, polycyclic aromatic hydrocarbon R = 0.9752, The correlation coefficient of UV predicted values were 0.9737 and 0.9818, respectively, indicating that the model has practical value
