GB/T 20975.28-2019 《Methods for chemical analysis of aluminium and aluminium alloys—Part 28:Determination of cobalt content—Flame atomic absorption spectrometry》 Related products

This standard specifies the determination of cobalt content in aluminum and aluminum alloys by flame atomic absorption spectroscopy (AAS), which is suitable for samples with a determination range of 0.005% to 12.0%. The method is to dissolve the sample with muriatic acid and nitric acid, and then determine the cobalt content at 240.7 nm. This standard provides an effective technical means for the accurate detection of cobalt content in aluminum alloy materials.
