| 中文摘要: |
| 研究了硝酸工业铂回收过滤器中铂族金属回收工艺。通过预处理、化学溶解、分子识别分离铑、化学沉淀等过程，实现了铂族金属的高效回收。对溶解过程的影响因素进行了探索和优化，试验了分子识别技术从复杂原料中优先提纯铑。在优化条件下，铂、钯和铑的回收率分别为97.20%、98.13%和92.63%。 |
| 英文摘要: |
| The recovery process of platinum group metals in platinum recovery filter in nitric acid industry was studied. Through pretreatment, chemical dissolution, molecular identification rhodium separation, chemical precipitation, etc., high-efficiency recovery of platinum group metals was realized. The factors affecting the dissolution process were explored and optimized, and the molecular recognition technology was tested to purify rhodium preferentially from complex raw materials. Under optimized conditions, the recoveries of platinum, palladium and rhodium were 97.20%, 98.13% and 92.63%, respectively |
