The GB/T 11848.14-1991 standard specifies a method for the determination of potassium and sodium in uranium ore condensates by flame atomic absorption spectroscopy (AAS). The standard applies to the determination of potassium and sodium in the content range of 0.0025% to 0.3%. After the sample is analyzed by sulfuric acid and hydrogen peroxide, the uranium is separated from potassium and sodium by strong alkaline anion exchange Resin, and finally determined by flame atomic absorption method. This standard applies to the analysis of uranium ore condensates, ensuring that the interference of Miscellaneous impurities during the determination process is negligible.
