| 中文摘要: |
| 硝酸工业产生的废铂合金催化网具有极高的经济价值。提出采用王水溶解-氯化铵沉淀分铂-氨水络合分钯-精炼工艺从废铂合金催化网中回收铂、钯和铑。结果表明，采用该工艺可获得纯度大于99.99%的海绵铂，纯度大于99.95%的海绵钯和铑粉；铂、钯、铑的直收率分别为98.6%、98.5%、97.1%。 |
| 英文摘要: |
| The waste platinum alloy catalytic gauze produced by the nitrate industry has extremely high economic value. It was proposed to recover platinum, palladium and rhodium from waste platinum alloy catalytic gauze by adopting the process of aqua regia dissolution-ammonium chloride precipitation for separating platinum-ammonia complexation for separating palladium-refining. The results show that the purity of sponge Pt, Pd and Rh are >99.99%, 99.95% and 99.95%, respectively, and their corresponding direct recovery rates are 98.6%, 98.5%, 97.1%. |
