    Paints and varnishes--Determination of “soluble” metal content--Part 7:Determination of mercury content of the pigment portion of the paint and of the liquid portion of water-dilutable paints--Flameless atomic absorption spectrometric method

    GB/T 9758.7-1988 "Paints and varnishes - Determination of 'soluble' metal content - Part 7: Determination of mercury content in the pigment portion of paints and in the liquid portion of water-dilutable paints - Flameless atomic absorption spectrometric method" specifies the method for determining the "soluble" mercury content in paints using flameless atomic absorption spectrometry, which is applicable to relevant coating products. The method utilizes the absorption characteristics of mercury atoms at specific wavelengths of light for quantitative detection through a flameless atomic absorption spectrometer. The detection requires the use of a flameless atomic absorption spectrometer, sample digestion equipment, an analytical balance, and volumetric flasks, providing technical support for the strict control of mercury elements in coatings.
