Method and apparatus for removing silver in the form of silver salts from a liquid |
| abstract |
By using a method of removing silver in the form of sparingly soluble silver salt, especially silver sulfide, from a solution containing another silver compound, such as a silver thiosulfate complex in a photographic fix or rinsing fluid by precipitation, the solution is subjected to electromagnetic irradiation with a wavelength below 375 nm. The irradiated liquid is led through a filter-like means 33 which binds the silver sulfide to its surface as crystalline silver sulfide. As a result, the silver sulfide is precipitated and deposited on the surface of the means as solid silver sulfide which in its turn acts as a catalyst for further precipitation and depositing of solid silver sulfide on the surface of the means. By binding the solid silver sulfide to the surface of the means, the required capacity of a possible subsequent filter is reduced. |
