GB/T 9758.2-1988 "Paints and varnishes - Determination of 'soluble' metal content - Part 2: Determination of antimony content - Flame atomic absorption spectrometric method and Rhodamine B spectrophotometric method" specifies two methods for determining the "soluble" antimony content in paints and varnishes, applicable to the testing of coating products. The flame atomic absorption spectrometric method quantifies antimony based on its characteristic absorption, while the Rhodamine B spectrophotometric method measures absorbance based on complexation reactions. The testing requires equipment such as flame atomic absorption spectrometers, spectrophotometers, digestion devices, and cuvettes, providing a technical standard for controlling antimony content in coatings.
