PROCESS OF RECOVERING SILVER FROM PHOTOGRAPHIC SOLUTIONS |
摘要 |
A process for removing silver from a silver containing photoprocessing solution, comprising the steps of: a) mixing a mercapto-s-triazine, or a water soluble salt thereof, with the solution thereby causing formation of a mixture of i) precipitates and fines of silver mercapto-s-triazine and ii) the solution; b) mixing a copolymer flocculant with the mixture thereby causing flocculation and agglomeration of the silver TMT fines; wherein the copolymer i) consist of monomers selected from the group consisting of acryloyloxyethyl trimethylamine chloride and acrylamide and ii) has a reduced viscosity of 21 to 30 dL/g.
