GB/T 5195.14-2017 《Fluorspar—Determination of magnesium content—Flame atomic absorption spectrometry》 Related products

This standard specifies a method for the determination of mg content in fluorite by flame atomic absorption spectroscopy (AAS) for samples with mg content in the range of 0.008% to 0.500%. The summary of the method includes the analysis of samples by hydrofluoric acid, perchloric acid and sulfuric acid, the use of strontium chloride as the Releasing agent, the measurement of mg Absorbance at a wavelength of 285.2 nm, and the calculation of mg content using the standard Linear dispersion method. The standard specifies reagents, instruments and operating procedures, providing technical support for the determination of mg content in fluorite.
