METHOD OF EXTRACTING PALLADIUM THROUGH EXTRACTION WITH BENZODITHIACROWN-ETHERS |
| 摘要 |
FIELD: chemistry. ^ SUBSTANCE: invention relates to the technology of extracting palladium from acid solutions. Method of extracting palladium is realised via extraction from chloride solutions into an organic phase with subsequent re-extraction. The extraction agent used is 0.01-0.02 mol/l solution of nitro-derivative or formyl derivatives of benzodithiacrown-compounds in dichloromethane. Re-extraction is carried out with 8-10% solution of thiourea in 0.01M hydrochloric acid solution. ^ EFFECT: high degree of palladium extraction. ^ 3 tbl, 2 ex |
