1.1 本试验方法包括在样品酸消解后，通过电感耦合等离子体原子发射光谱法（ICP-AES）测定废物流中的痕量、微量和常量元素。可以分析核材料和非核材料制造过程中的废物流。本试验方法适用于总金属的测定。该试验方法的结果可用于表征处理设施接收的废物，并制定适当的处理配方。研究结果也可用于废物处理设施内的过程控制。 1.2 本试验方法仅适用于放射性水平不需要特殊人员或环境保护的废物流。 1.3 废物流中确定的元素列表和相应的报告下限见 表1 . 1.4 该试验方法已成功用于处理各种废液和工业过程液体。无论是在废物流类型之间还是在单个废物流内，此类样品的成分都是高度可变的。由于这种可变性，单个酸消解方案可能无法在所有样品基质中成功。某些元素可以在半定量的基础上回收，而大多数结果将是高度定量的。 1.5 本试验方法应由在ICP-AES的使用、光谱和非光谱干扰的解释以及校正程序方面有经验的分析员使用。 1.6 由于适用ICP-AES仪器的不同品牌和型号之间存在差异，因此未提供详细的操作说明。 相反，分析员应遵循特定仪器制造商提供的说明。本试验方法不涉及不同装置的比较精度或相同品牌和型号仪器之间的精度。 1.7 本试验方法包含解释性注释，不属于该方法强制性要求的一部分。 1.8 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.9 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.10 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 本试验方法适用于测定各种核和非核制造工艺产生的许多废物流中的金属浓度。该试验方法可用于在处理、储存或稳定之前表征液体废物和含有未溶解固体的液体废物。它能够同时测定多达26种元素。 5.2 本程序分析的元素的适用浓度范围列于 表1 .

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) following 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 determination 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 personnel 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 treatment of a large variety of waste 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 quantitative. 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 instruments 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 appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.10 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 This test method is useful for the determination of concentrations of metals in many waste streams from various nuclear and non-nuclear manufacturing processes. The test method is useful for characterizing liquid wastes and liquid wastes containing undissolved solids prior to treatment, storage, or stabilization. It has the capability for the simultaneous determination of up to 26 elements. 5.2 The applicable concentration ranges of the elements analyzed by this procedure are listed in Table 1 .
