| 中文摘要: |
| 采用分子识别材料SuperLigò2从含铂钯的溶液中选择性分离钯，钯吸附率大于99%，吸附、洗脱过程钯的直收率为95.87%，总收率为98.04%；得到的洗脱液氧化处理后生成钯沉淀，再经水合肼还原即可得到纯度为99.99%的钯粉。与传统的沉淀分离工艺相比，分子识别技术的生产流程短、铂不容易分散、操作方便、三废量少。 |
| 英文摘要: |
| The molecular recognition material SuperLigò2 was used to selectively separate palladium from the solution containing platinum and palladium. The adsorption rate of palladium was more than 99%, and the direct yield of palladium was 95.87%, and the total yield was 98.04%. The obtained palladium eluent was oxidized to obtain palladium precipitation, which is then reduced by hydrazine hydrate to obtain palladium powder with a purity of 99.99%. Compared with the traditional precipitation separation process, the molecular recognition technology has a shorter production process, less platinum dispersion, convenient operation and less waste. |
