| titleOfInvention | Method for platinum-perrhenic catalysts processing |
| abstract | FIELD: chemistry. n SUBSTANCE: method involves catalysts calcination at a temperature of 600-850°C, re-firing at a temperature of 1200-1300°C with capture of rhenium compounds. Then, platinum is leached from the cinder and the insoluble residue is washed in hydrochloric acid, with addition of nitric acid as an oxidizer, until the oxidation-reduction potential in the pulp with respect to the silver chloride reference electrode equal to 780-840 mV is reached. n EFFECT: reduced consumption of nitric acid with the required full extraction of platinum. n 1 tbl, 1 ex |
