适用范围：1 This International Standard specifies an ana-lytical method for determining the fluorine content in uranium metal, uranium dioxide powder and pel-lets and solutions of uranyl nitrate.2 The method can be used within the concen-tration range of 1 pg to 0,01 g of fluorine per gram of the sample. Impurity levels of up to 300 pg of boron and 3 000 pg of silicon, aluminium and iron in the final measured solution can be tolerated. Zirconium interferes seriously and should be ab-sent. The applicability of the method to samples containing significant impurity levels can be con-firmed by modifying the basic procedure.
