GB/T 20899.2-2019 《Methods for chemical analysis of gold ores一Part 2:Determination of silver content 一Flame atomic absorption spectrometric method》 Related products

This standard specifies a method for the determination of silver content in gold ores by flame atomic absorption spectroscopy (AAS), suitable for the determination of silver content in the range of 2.00 g/t to 1000.0 g/t. After the sample is treated with muriatic acid, nitric acid, perchloric acid and hydrofluoric acid, the measurement Absorbance at a wavelength of 328.1 nm is used to calculate the silver content. This method provides effective technical support for the accurate determination of silver content in gold ores.
