| 中文摘要: |
| 建立了碱熔分解样品、碲共沉淀分离，电感耦合等离子体发射光谱法(ICP-AES)测定含钌二次资源物料中钌含量的方法。对样品分解、钌的分离和测定、方法准确度和精密度进行了研究。约0.5 g粉末样品与5 g的过氧化钠混匀，于730 ℃马弗炉中熔融25 min，冷却后用水浸出，盐酸酸化，加氧化剂使钌保持较高价态，用碲共沉淀法分离钌，ICP-AES测定钌含量。样品加标回收率98.8%~99.8%，相对标准偏差(RSD，n=9)为:0.3%~1.0%，方法快速、简便，已应用于生产测定。 |
| 英文摘要: |
| A method was established for the determination of ruthenium contents in secondary ruthenium resource by ICP-AES after alkali fusion-tellurium coprecipitation. The decomposition of the sample, the separation and determination of ruthenium, the accuracy and precision of method were systematically investigated. The sample (0.5g) was pretreated by the following procedures to produce a solution: mixing with 5 g sodium peroxide, melting in muffle furnace at 730 ℃ for 25 min, leaching with water after cooling, acidifying with hydrochloric acid, adding oxidant to keep ruthenium in a higher valence state. Ruthenium was separated from the solution by tellurium coprecipitation and then submitted for ICP-AES measurement. The spiked recovery was found to be 98.8%~99.8% and the relative standard deviation (RSD, n=9) was 0.3%~1.0%. The established method is simple and time-saving, and can be applied to the analysis of the ruthenium contents in secondary resource. |
