贵金属材料分析

论述了贵金属材料分析的重要性和特殊性，指出应根据材料的类型和对分析的要点，优先考虑解决如测定贵金属元素的准确度、选择性或方法的灵敏等问题。评述了自１９９２年以来国内贵金属材料分析的发展，内容包括高含量、低含量和高纯贵金属材料的分析。涉及的分析技术主要有滴定法、精密库仑滴定法、等离子体－发射光谱法、原子吸收光谱法和光度法等。

Analysis of Precious Metal Materials

The importance and peculiarity on the analysis of precious metal materials is emphasizes in this paper. Based on the different kinds of materials to be analyzed and the requirement for the analysis, some major points such as accuracy, selectivity or the sensitivity for the determination of precious metal elements should be considered preferentially. The development on the analysis of precious metal materials in China during the period of 1992 to 1998 has been reviewed. The analysis of different materials both with high and low contents of precious metals as well as the pure precious metal material analysis is involved. The main analytical techniques are titrimetry, precise coulometric titration, inductively coupled plasma atomic emission spectrometry, atomic absorption spectrometry and spectrophotometry. 112 references are also cited.
