GB/T 11066.4-2008 《Methods for chemical analysis of gold - Determination of copper, lead and bismuth contents - Flame atomic absorption spectrometry》 Related products
This standard applies to the simultaneous determination or separate determination of copper, lead and file elements in gold. The determination scope is detailed in Table 1. Using flame atomic absorption spectroscopy (AAS), after analysis of the sample by aqua regia, the gold was extracted and separated by ethyl acetate, and then the aqueous phase was determined. This standard provides detailed reagent preparation and instrument use conditions to ensure the accuracy and Repeatability of detection.
