| 中文摘要: |
| 在粗铂提纯精炼过程中通常加入过量丁二酮肟除钯，使钯以丁二酮肟合钯形态沉淀。针对除钯渣中钯的回收，传统回收方法是直接将丁二酮肟合钯高温焚烧分解得到氧化钯，再进一步精炼提纯得到纯钯，但该方法钯回收率低，焚烧挥发损失大，烟气环境污染严重。实验采用碱液浆化-还原-钯精炼-丁二酮肟再生四个步骤可有效回收钯及丁二酮肟。实验结果表明，回收的钯纯度大于99.95%，回收率大于99.0%，丁二酮肟纯度大于99%。 |
| 英文摘要: |
| In the purification process of crude platinum, excessive butadione oxime is usually added to remove palladium impurities from platinum, and a slag containing palladium in the form of the complex of butadione oxime is produced. For the recovery of palladium from the slag, the traditional method is to directly decompose the complex at a high temperature, followed by further refinement and purification. However, a lower recovery rate of palladium is obtained due to the volatile loss of the organic complex and an environmental pollution caused by emission of flue gases is accompanied. In this experimental a four-step process was adopted involving alkaline pulp, reduction and refining of palladium, and regeneration of budione oxime The experimental results showed that the recovery rate of palladium exceeded 99.0%, with a purity of 99.95% for palladium and 99% for budione oxime. |
