摘要： It is known to treat the effluent resulting from photographic processing apparatus. Such treatment takes the form of either neutralization where the effluent is mixed with a neutralizing solution prior to disposal, or evaporation where the effluent is heated to form a precipitate and a concentrated liquid portion prior to disposal. However, both these techniques have disadvantages they do not account for toxic particles which may be suspended in the solutions. Described herein is apparatus in which photographic effluent can be treated to provide harmless end products which can be disposed of directly. The apparatus comprises a mixing unit (10) in which the effluent (S1) is mixed with treatment chemicals (S2, S3, S4, P1, P2, P3) and is then passed to a separation unit (20) in which the treated effluent is separated into non-toxic liquid and solid phases. A computer (100) is used to control all stages of the treatment of the effluent.

摘要： A process for regenerating spent bleach fixer by recovering silver sulfide from a spent solution is described. The process is particularly suited for treating the bleach fixer solution in a manner which enables recycling of the solution giving rise to considerable reduction in cost of bleach fixer solution and reduced environmental pollution. The process comprises introducing a hydrosulfide reagent into the bleach fixer solution, which contains silver, to precipitate silver sulfide while maintaining pH and thiosulfate levels in the bleach fixer to allow for reuse. The precipitate is isolated from the bleach fixer solution to remove silver thereby and hence enable recycling of the bleach fixer solution. It is preferred to adjust the pH and sulfite levels following silver removal to complete the regeneration process.

摘要： Method for recovering metal from a solution containing ions of the metal and complexing agent for the ions. The method involves contacting the solution with another metal more electropositive than the metal to be recovered in order to bring about a metal-metal exchange reaction which will yield a precipitate of the metal to be recovered. The precipitate is then separated from the solution. In order to maximize the yield of the metal-metal exchange reaction, the redox potential of the solution is measured during the reaction, and the precipitate is separated from the solution when the redox potential substantially reaches a predetermined minimum value.

摘要： The invention resides in treating an image-wise exposed and colour developed photographic element with a bleaching agent and a fixing agent. The fixing agent comprises an aliphatic thiol as accelerator. The accelerator present in the fixing agent both stabilizes the fixing agent so that it can be used commercially and prevents staining resultant upon the degeneration of the thiol in the bleach fix bath. The invention also provides a means for efficient silver removal from the fixing bath thereby obviating a separate silver removal stage.

摘要： 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.
