1.1 本试验方法包括通过原子吸收光谱法测定水中的溶解锑和总可回收锑。 2. 1.2 本试验方法适用于1至15μg/L锑。可通过减少标度膨胀或稀释样品来扩大范围。 1.3 获得了试剂水、自来水、盐水和两种未处理废水的精度和偏差数据。有关精度和偏差的信息可能不适用于其他水域。 1.4 以国际单位制表示的数值应视为标准值。括号中给出的值是英寸-磅单位的数学转换，仅供参考，不被视为标准值。 1.5 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和健康实践，并确定监管限制的适用性。 1.6 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 由于在工业中与铅和砷有关，通常很难评估锑及其化合物的毒性。在人类中，有报告称与神经系统有关的投诉。 然而，在评估人类病例时，必须始终牢记铅或砷中毒的可能性。局部锑化合物对皮肤和粘膜有刺激性。 5.2 ICP-MS也适用，但仪器成本较高。见测试方法 D5673 .

1.1 This test method covers the determination of dissolved and total recoverable antimony in water by atomic absorption spectroscopy. 2 1.2 This test method is applicable in the range from 1 to 15 μg/L of antimony. The range may be extended by less scale expansion or by dilution of the sample. 1.3 The precision and bias data were obtained on reagent water, tap water, salt water, and two untreated wastewaters. The information on precision and bias may not apply to other waters. 1.4 The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound units that are provided for information only and are not considered standard. 1.5 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. 1.6 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 Because of the association with lead and arsenic in industry, it is often difficult to assess the toxicity of antimony and its compounds. In humans, complaints referable to the nervous system have been reported. In assessing human cases, however, the possibility of lead or arsenic poisoning must always be borne in mind. Locally, antimony compounds are irritating to the skin and mucous membranes. 5.2 ICP-MS may also be appropriate but at a higher instrument cost. See Test Method D5673 .
