GB/T 8152.16-2022 《Methods for chemical analysis of lead concentrates—Part 16: Determination of calcium oxide content—Flame atomic absorption spectrometric method》 Related products

This standard specifies a method for the determination of calcium oxidation content in lead concentrates by flame atomic absorption spectroscopy (AAS). This method is suitable for the determination of calcium oxidation content in lead concentrates in the range of 1.00% to 5.00%. Absorbance measurement of calcium at a wavelength of 422.7 nm using an air-acetylene flame through the acidification of the sample and the suppression of interfering elements is used to calculate the calcium oxidation content. This standard provides clear test methods and technical requirements for the chemical analysis of lead concentrates.
