CATALYST FOR EXTRACTION OF COPPER FROM SPENT SOLUTIONS AND METHOD OF ITS PRODUCTION |
| 摘要 |
<p>FIELD: production of catalysts, applicable for extraction of copper from solutions, industrial sewage and sewage water. SUBSTANCE: catalyst contains 0.5 to 5.0 mass percent of copper on carbon carrier having a high specific surface. This catalyst is obtained by precipitation of metal on carrier by impregnation of carrier with a solution of complex copper salt - diammine hypophosphite dihidrate with a subsequent heat treatment at 90 to 150 C for 10 to 30 min. EFFECT: enhanced efficiency. 2 cl, 1 tbl</p> |
