Standard Test Method for Trace Uranium in Water by Pulsed-Laser Phosphorimetry
Show Complete Document History
The following bibliographic material is provided to assist you with your purchasing decision:
1.1 This test method covers the determination of total uranium, by concentration, in water within the calibrated range of the instrument, 0.1 μg/L or greater. Samples with uranium by mass, levels above the laser phosphorimeter dynamic range are diluted to bring the concentration to a measurable level.
1.2 This test method was used successfully with reagent water. It is the user's responsibility to ensure the validity of this test method for waters of untested matrices.
1.3 The values stated in SI units are to be regarded as the standard.
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.
Significance and Use
5.1 This test method is useful for the analysis of total uranium in water following wet-ashing, as required, due to impurities or suspended materials in the water.
