SILVER RECOVERY ELEMENT AND METHOD |
| 摘要 |
<p>A silver recovery element (10) for treating a photographic developer solution containing silver ions comprises a substrate (20) having thereon a hydrophilic colloid layer containing physical development nuclei. The invention also comprises a process for recovering silver from a photographic developer solution containing silver ions, such process comprising contacting the solulion with the silver recovery element. The contacting is for a time sufficient to reduce the concentration of silver in the solution to a desired level. The recovery element and process for its use are useful in treating a a seasoned photographic developer solution containing silver ions.</p> |
