GB/T 7739.2-2019 《Methods for chemical analysis of gold concentrates—Part 2:Determination of silver content—Flame atomic absorption spectrometric method》 Related products

This standard specifies a method for the determination of silver content in gold concentrates by flame atomic absorption spectroscopy (AAS), applicable to the determination of silver content in the range of 10.00 g/t to 2000.0 g/t. Samples treated with muriatic acid, nitric acid and perchloric acid are measured at a wavelength of 328.1 nm to calculate silver content. This standard provides a standardized method for the quantitative analysis of silver content in gold concentrates.
