| 中文摘要: |
| 研究使用工业纯氯化铵替代试剂级氯化铵沉淀氯铂酸铵，获得SM-Pt 99.95纯度的海绵铂产品。使用工业氯化铵分别对铂解吸液和含银铂溶液进行精炼，结果显示，在不改变工艺路线不增加精炼次数的前提下，经过2~3次反复沉淀氯铂酸铵精炼，得到合格海绵铂产品，与使用试剂级氯化铵相比，铂精炼试剂成本降低80%，获得较好经济效益。 |
| 英文摘要: |
| The study used industrial grade ammonium chloride instead of analytial reagent grade ammonium chloride to precipitate ammonium chloroplatinate to obtain platinum sponge of SM-Pt 99.95 purity. Using industrial grade ammonium chloride to refine platinum desorption solution and silver-containing platinum solution respectively, the results showed that under the premise of not changing the process route and not increasing the number of refining times, qualified platinum sponge products are obtained after 2 to 3 repeated precipitation of ammonium chloroplatinate, and compared with the use of analytial reagent grade ammonium chloride, the cost of reagents for platinum refining is reduced by 80%, which yields better economic benefits. |
