    Paints and varnishes--Determination of “soluble” metal content--Part 6:Determination of total chromium content of the liquid portion of the paint--Flame atomic absorption spectrometric method

    GB/T 9758.6-1988 "Paints and varnishes - Determination of 'soluble' metal content - Part 6: Determination of total chromium content in the liquid portion of paints - Flame atomic absorption spectrometric method" specifies the method for determining the total chromium content in the liquid portion of paints using flame atomic absorption spectrometry, applicable to relevant coating products. The method involves digesting the sample, utilizing the atomic absorption characteristics of chromium, and measuring absorbance at a specific wavelength for quantification. The detection requires the use of a flame atomic absorption spectrometer, sample digestion equipment, an analytical balance, and volumetric flasks, standardizing the testing process for total chromium content in paints.
