Recent advances in digestion methods used in the analysis of precious metal samples by spectrometric techniques are reviewed. The applicability of a fire assay, a wet acid treatment, chlorination and alkaline oxidizing fusion to a quantitative recovery of metals from various materials is discussed. Data on the precious metal contents obtained by using particular digestion methods as well as UV-VIS spectrophotometry, atomic absorption spectrometry, atomic emission spectrometry and inductively coupled plasma mass spectrometry in the examination of various samples are tabulated.
综述了光谱技术分析贵金属样品时所用消化方法的最新进展。讨论了火试金法、湿酸处理、氯化法和碱性氧化熔融法从各种材料中定量回收金属的适用性。列出了在各种样品检测中使用特定消化方法以及紫外可见分光光度法、原子吸收光谱法、原子发射光谱法和电感耦合等离子体质谱法获得的贵金属含量数据。
