GB/T 14949.2-2021 《Manganese ores—Determination of nickel content—Flame atomic absorption spectrometric method》 Related products

This standard specifies a method for the determination of nickel content in manganese ores using flame atomic absorption spectroscopy (AAS), suitable for the determination of manganese ore samples with a nickel content range of 0.005% to 0.200%. The nickel content is determined by dissolving the sample, treating it and measuring Absorbance at a specific wavelength. This standard provides specifications for the accurate detection of nickel content in manganese ores, ensuring the accuracy and conformity of analytical results.
