摘要
贵金属的"二次资源"中含有大量的贵金属,回收其中的贵金属不仅可以避免环境污染,而且可以节约资源,具有重要的经济价值。介绍了从不同种类贵金属废料中回收贵金属技术和适于检测其含量方法的主要进展,简要论述了各种方法的优缺点,并对其发展趋势做出展望。
Some secondary resources contain large amount of noble metals,the recovery of which can not only avoid environmental pollution but also save resources,yielding much economic value.We describe the research progress in the technologies to recover and measure the trace noble metals from all kinds of waste metals,briefly discuss the advantages and disadvantages of various methods.We also come up with a prospect on the further studies in this field.
