This standard describes a high-performance liquid chromatograph detection method for the content of UV-320 and UV-328 UV absorbers in solar-based paints and water-based paints. It is suitable for the determination of the content of UV-320 and UV-328 UV absorbers in solar-based paints and water-based paints. The lower limit of the determination is 25 mg/kg. The principle is to detect the content of UV-320 and UV-328 by solvent extraction and Liquid chromatography, LC determination. Reagents and materials include ethyl acetate, n-hexane, tetrahydrofuran, acetonitrile, and standard substances of UV-320 and UV-328, etc.
