Historical Standard: ASTM C1432-99 Standard Test Method for Determination of Impurities in Plutonium: Acid Dissolution, Ion Exchange Matrix Separation, and Inductively Coupled Plasma-Atomic Emission Spectroscopic (ICP/AES) Analysis
SUPERSEDED (see Active link, below)
ASTM C1432
1. Scope
1.1 This test method covers the determination of 25 elements in plutonium (Pu) materials. The Pu is dissolved in acid, the Pu matrix is separated from the target impurities by an ion exchange separation, and the concentrations of the impurities are determined by inductively coupled plasma-atomic emission spectroscopy (ICP-AES). The elements determined are listed in Table 2.
1.2 This test method is specific for the determination of impurities in Pu in 8 M nitric acid (HNO 3 ) solutions. Impurities in other plutonium materials, including plutonium oxide samples, may be determined if they are appropriately dissolved (see Practice C 1168) and converted to 8 M HNO 3 solutions.
1.3 Plutonium bearing materials are radioactive and toxic. Adequate laboratory facilities, glove boxes, and fume hoods, along with safe techniques, must be used in handling samples containing these materials. A detailed discussion of all the precautions necessary is beyond the scope of this test method; however, personnel who handle these materials should be familiar with such safe handling practices.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
