描述信息通信技术商品中稀有金属特征的衡量方法 |
信息通信技术商品由许多部件和模块构成,含有相对较少的稀有金属和大量的主要材料(如,铁、有色金属、塑料、玻璃和工程陶瓷)。这些材料是通过复杂的生产程序生产的。要建立有效的回收系统,生产商必须提供准确的稀有金属信息。但是,获取ICT产品中稀有金属成分的信息可能使用许多测量和定性方法。而每种方法在分析这些成分的信息是各有利弊。根据所用的测量方法的不同,成分分离能力和定量分解则不尽相同,对确定稀有金属的定量和定性没有标准化的测量方法。但是,IEC 62321为x射线荧光(XRF)和电感耦合等离子体质谱(ICP-MS)的测量方法提供一些指南,以便对不明样本和有害物质进行定性和定量分析。在IEC 62321指南的基础上,ITU-T L.1101号建议书为利用XRF和ICP-MS测量方法对稀有金属进行有效回收提供了一个参考性的定性程序。 |
