GB/T 1871.5-2022 《Determination of magnesium oxide content for phosphate rock and concentrate—Flame atomic absorption spectrometry，volumetry and inductively coupled plasma optical emission spectrometry》 Related products

This standard specifies three methods - flame atomic absorption spectroscopy (AAS), volumetric method and inductively coupled plasma emission Light spectrum method for the determination of oxidation mg in phosphate rocks and phosphate concentrates. These methods are suitable for the determination of oxidation mg in different content ranges. The specific measurement ranges are detailed in Table 1 of the standard. The standard provides scientific test methods and technical guidance for the determination of oxidation mg content of phosphate rocks and their concentrate products to ensure the accuracy and reliability of the detection.
