Method for selectively removing antimony and bismuth from sulphuric acid solutions |
| 摘要 |
A method of purifying sulphuric acid solns. having a concn. of at least 50g/l and contg. ferric ions and at least one of antimony ions and bismuth ions is claimed. The ferric ions are first reduced to ferrous ions and then antimony and bismuth ions are selectively removed by passing the soln. through an ion exchange resin (IER). The purified sulphuric acid soln. is then recovered. |
