试样用硝酸及盐酸溶解,加盐酸赶除硝酸,用溴酸钠氧化,在碳酸氢钠(pH8)溶液中,钯、铑呈水合氧化物形式沉淀,铂却留在溶液中。滤出沉淀溶于盐酸中,再重复溴酸钠氧化沉淀一次,使钯、铑与铂完全分离。再将钯、铑的沉淀溶于盐酸中,在约3%盐酸溶液中,加丁二肟乙醇溶液沉淀钯,过滤与铑分离,用烘干丁二肟钯的沉淀的重量法测定钯量。滤液中的铑量,用氯化亚锡分光光度法测定之。 本方法适用于分析铂钯铑合金中4%钯及3.5%铑。

1.1 This specification covers refined cadmium metal in slab, ball or stick form. 1.2 Toxicity—Warning: Soluble and respirable forms of cadmium may be harmful to human health and the environment in certain forms and concentrations. Therefore, ingestion and inhalation of cadmium should be controlled under the appropriate regulations of the U.S. Occupational Safety and Health Administration (OSHA). Cadmium-containing alloys and coatings should not be used on articles that will contact food or beverages, or for dental and other equipment that is normally inserted in the mouth. Similarly, if articles using cadmiumcontaining alloys or coatings are welded, soldered, brazed, ground, “flame-cut,” or otherwise heated during fabrication, adequate ventilation must be provided to maintain occupational cadmium exposure below the OSHA Permissible Exposure Level (PEL). 1.3 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered 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 become familiar with all hazards including those identified in the appropriate Safety Data Sheet (SDS) for this product/material as provided by the manufacturer, to establish appropriate safety, health, and environmental practices, and determine the applicability of regulatory limitations prior to use. 1.5 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.
