分析钯钌合金的最大难点在于制备样品,因为这种合金通常只能溶于王水,而且钌极易挥发损失,难以准确地定量测定。本文采用电移谱法制备样品,避免了湿法分解样品的缺点。并将该法同环炉分离技 The biggest difficulty in analyzing palladium-ruthenium alloys is the preparation of samples because the alloy is usually only soluble in aqua regia and ruthenium is very volatile and difficult to accurately measure. In this paper, the use of electric spectrum method to prepare samples, to avoid the wet decomposition of the shortcomings of the sample. And the method with ring furnace separation technology
