Paints and varnishes--Determination of “soluble” metal content--Part 3:Determination of barium content--Flame atomic emission spectrometric method

GB/T 9758.3-1988 "Paints and varnishes - Determination of 'soluble' metal content - Part 3: Determination of barium content - Flame atomic emission spectrometric method" specifies the method for determining the 'soluble' barium content in paints and varnishes using flame atomic emission spectrometry. It is applicable to various types of coating products. After digestion, the sample is excited by a flame to produce characteristic emission spectra from barium atoms, and the emission intensity is measured for quantification. The detection requires the use of a flame atomic emission spectrometer, digestion apparatus, analytical balance, and volumetric flasks, providing a standardized basis for the detection of barium content in coatings.
