1. Scope
1.1 This test method covers the determination of trace, minor, and major elements in waste streams by inductively coupled plasma-atomic emission spectroscopy (ICP-AES) fol- lowing an acid digestion of the sample. Waste streams from manufacturing processes of nuclear and non-nuclear materials can be analyzed. This test method is applicable to the deter- mination of total metals. Results from this test method can be used to characterize waste received by treatment facilities and to formulate appropriate treatment recipes. The results are also usable in process control within waste treatment facilities. 1.2 This test method is applicable only to waste streams that contain radioactivity levels that do not require special person- nel or environmental protection. 1.3 A list of the elements determined in waste streams and the corresponding lower reporting limit is found in Table 1. 1.4 This test method has been used successfully for treat- ment ofa large variety ofwaste solutions and industrial process liquids. The composition of such samples is highly variable, both between waste stream types and within a single waste stream. As a result of this variability, a single acid digestion scheme may not be expected to succeed with all sample matrices. Certain elements may be recovered on a semi- quantitative basis, while most results will be highly quantita- tive. 1.5 This test method should be used by analysts experienced in the use of ICP-AES, the interpretation of spectral and non-spectral interferences, and procedures for their correction. 1.6 No detailed operating instructions are provided because of differences among various makes and models of suitable ICP-AES instruments. Instead, the analyst shall follow the instructions provided by the manufacturer of the particular instrument. This test method does not address comparative accuracy of different devices or the precision between instru- ments of the same make and model. 1.7 This test method contains notes that are explanatory and are not part of the mandatory requirements of the method. 1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.9 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 appro- priate safety, health, and environmental practices and deter- mine the applicability ofregulatory limitations prior to use. 1.10 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
8. Reagents
8.1 Purity ofReagents—Chemicals used in the preparation of the standards must be of ultrahigh purity grade. Chemicals used in the preparation of the samples shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, 6 where such specifications are available. 8.2 Purity ofWater—Unless otherwise indicated, references to water shall be understood to mean reagent water as defined by Specification D1193, Type I, or water exceeding these specifications. 8.3 Nitric Acid (sp gr 1.42)—Concentrated nitric acid (HNO 3 ). 8.4 Nitric Acid, 10 Volume %—One volume of concentrated nitric acid (specific gravity 1.42) brought to ten volumes with water. 8.5 Stock Solutions—Standard stock solutions may be pur- chased or prepared from ultrahigh purity grade metals or metal salts (Method 6010, SW-846). All salts must be dried for 1 h at 105 °C unless otherwise specified. Stock solutions should contain approximately 1000 to 10 000 mg/L of the element of interest to ensure long term stability in dilute nitric acid.
