This standard specifies the method for screening chromium-containing pigments in Coatings by Inductance-coupled Plasma Atomic Emission Spectroscopy (AES). It is suitable for screening chromium yellow, lead chromate, and molybdenum chromium red pigments in Coatings, but not for chromium green Coatings. The summary of the method includes that after the Coating is film dried, all organic substances are removed by microwave digestion method, and then determined by Inductance-coupled Plasma Atomic EmissionSpectrometer, and finally the chromium content is calculated according to the working Linear dispersion. The reagents and materials should be analytically pure, and the distillation water or deionized water should meet the requirements of GB/T6682 secondary water. Reference files include GB/T 602, GB/T 6682, GB/T 8170, and GB/T 23942.
