本文研究了贵金属含量较高的贵金属粉末中的贵金属元素的直接快速测定方法 ,研究了试样分解方法、测定介质的影响、元素间的光谱干扰。拟定了最佳工作条件 ,对进出口实际样品进行了分析 ,其结果与原子吸收光谱及光度法的测试结果一致性较好。
In this paper, a direct and rapid method for the determination of noble metals in noble metal powders with higher noble metal content is studied. The methods of sample decomposition, the influence of medium and the spectral interferences between elements are studied. The best working conditions were worked out and the actual samples of import and export were analyzed. The results were in good agreement with the results of atomic absorption spectrometry and photometry.
