利用无火焰原子吸收保证很高绝对灵敏度的雾化方法乃是测定贵金属时的实际需要。因为,这些元素在天然材料中的含量一般为10~(-4)——10~(-7)％。本论文是研究用《》公司出品的,附有HGA——74型石墨炉原子化器的530型原子吸收光谱仪,测定复杂组份溶液中低含量金、银、铂和钯的可能性。用HGA型石墨炉研究物理——化学过程的成果已有不少文章报道,但涉及到贵金属的资料很有限。
The atomization method, which guarantees a high absolute sensitivity using flameless atomic absorption, is the actual need to measure precious metals. Because, these elements in the natural material content is generally 10 ~ (-4) - 10 ~ (-7)%. This paper is a study of the possibility of determining the low levels of gold, silver, platinum and palladium in solutions of complex components by the “530” atomic absorption spectrometer manufactured by the company “HGA - 74 Graphite Furnace Atomizer”. There have been many articles on the results of physical-chemical processes using HGA-type graphite furnaces, but there is limited information on precious metals.
