ICS Code (Fissile materials and nuclear fuel technology): 27.120.30
scope:

1. Scope

1.1 These test methods are applicable to the determination of total arsenic in uranium hexafluoride (UF6) by atomic absorption spectrometry. Two test methods are given: Test Method A--Amine Generation-Atomic Absorption (Sections 5 to 10), and Test Method B--Graphite Furnace Atomic Absorption (Sections 11 to 16).

1.2 The test methods are equivalent. The limit of detection for each test method is 0.1 µg As/g U when using a sample containing 0.5 to 1.0 g U.

1.3 Test Method A covers the measurement of arsenic in uranyl fluoride (UO2F2) solutions by converting arsenic to arsine and measuring the arsine vapor by flame atomic absorption spectrometry.

1.4 Test Method B utilizes a solvent extraction to remove the uranium from the UO2F2 solution prior to measurement of the arsenic by graphite furnace atomic absorption spectrometry.

1.5 Both insoluble and soluble arsenic are measured when UF6 is prepared according to Test Method C 761.

1.6 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.
