摘要:
试验用铂钯渣是铜阳极泥精炼过程中产生的冶炼渣，建立铂钯渣中钌、铑检测方法对提高该冶炼渣中贵金属的回收极为重要。以河南某铜冶炼厂的铂钯渣为检测对象，采用锌粒在高温下对样品碎化，盐酸溶解碎化产物获得富集物，并用过氧化钠熔融，定容后采用电感耦合等离子体原子发射光谱法测定，选择Ru 245.553 nm、Rh 343.489 nm作为分析谱线。结果表明，钌、铑测定结果的相对偏差为1.10%～2.20%，加入标准物质回收率为99.67%～100.33%，精密度和准确度好。

Abstract:
Platinum-palladium slag used in the experiment is the smelting slag produced in the refining process of copper anode sludge.It is very important to establish the determination method of ruthenium and rhodium in platinum-palladium slag to improve the recovery of precious metals in the smelting slag.Taking the platinum-palladium slag of a copper smelter in Henan as the detection object,zinc particles were used to crush the sample at a high temperature,and the crushed products were dissolved in hydrochloric acid to obtain enrichment that is fused by sodium peroxide.Finally,the constant volume was determined by ICP-AES,and Ru 245.553 nm and Rh 343.489 nm were used as the analytical spectral lines.The results show that the relative deviations (RSD) of ruthenium and rhodium were 1.10 %-2.20 %,and the recoveries of reference materials were 99.67 %-100.33 %.The method has good precision and accuracy.
