| 中文摘要: |
| 铑的高效快速溶解是铂族金属冶金领域不可或缺的环节，并且是公认的难题。微波具有热效应及非热效应的特点，在微波辅助溶解下能够使溶解体系的温度、压力迅速提高并保持稳定；同时微波作用可以降低溶解反应活化能，提高了溶液体系中活性氯与铑的化学反应速度。采用微波辅助高效溶解工艺，在王水浓度50%、体系压力4.0 MPa、溶解时间120 min的条件下，铑的溶解率达到99.5%。 |
| 英文摘要: |
| The high efficient and quick dissolution of rhodium is an indispensable part and a recognized problem in the field of rhodium metallurgy. Microwave has the characteristics of thermal effect and non-thermal effect. Temperature and pressure in the dissolution system are rapidly increased and remain stable under microwave assisted dissolution. Meanwhile, microwave effect can reduce the reaction activation energy, and improve the chemical reaction rate between active chlorine and rhodium in the solution system. Under the conditions of aqua regia concentration 50%, system pressure 4 MPa and dissolution time 120 min, the dissolution rate of rhodium is 99.5% by microwave assisted dissolution. |
