PROCESS FOR EXTRACTING HALOGENOUS IONS FROM FIXING BATHS USED IN PHOTOGRAPHY |
| abstract |
The invention relates to a process for the selective extraction of halide ions from photographic fixing solutions. The method comprises contacting the photographic fixing solution with a liquid membrane comprising a solvent and a crown ether transporter capable of transporting the halide ions from the fixing solution into an aqueous solution which thereby becomes charged with halides, and is then eliminated. Application to the recycling of fixing solutions. |
