| titleOfInvention | A process for recovering silver from waste film based on protease elution method |
| abstract | The invention belongs to the field of chemical manufacturing industry/applied chemistry, in particular to a process for recovering silver from waste films based on a protease elution method. The existing methods have problems such as environmental pollution, high investment, complicated operation, long cycle and the like. The following scheme is proposed, which includes the following steps: S1: raw materials and reagents: prepare waste film, Novozymes complex protease, concentrated nitric acid, hydrochloric acid, sodium chloride, polyacrylamide and agar; mix concentrated nitric acid, hydrochloric acid, sodium chloride, The stearic acid solution is prepared by mixing polyacrylamide and agar; S2: instrument and equipment, the invention does not cause environmental pollution, has short extraction period and low cost. High-purity silver ingots can be extracted, turning waste into treasure, saving resources, and simple subsequent sewage treatment. It has absolute feasibility and social and economic benefits. |
