  • Patent number: 9394584
    Abstract: A process for recovery of silver from silver-containing photographic emulsion-coated films, particularly films with paper or polymeric substrates. The process includes immersing photographic silver emulsion coated substrates, particularly paper, in a water-based solution of sodium hydroxide and sodium borohydride, with sufficient presence of an alkali metal hydroxide to maintain the solution at a pH of 11.0 to 12.0. Silver-containing emulsion layers are stripped from the substrate, while gelatin and other adhesive layers are dissolved. Silver present in a silver halide form is reduced to form metallic silver. The silver-laden emulsion is then treated using a polyamine coagulant and flocculant to induce precipitation of solids, particularly metallic silver, out of the solution. The exposure time of the paper to the wash bath is carefully controlled to permit recovery of the paper substrate.

  • Patent number: 6334944
    Abstract: An amino acid-N,N-diacetic acid (AADA) or its salt with an equivalent or less of an alkali metal is produced by reducing, through electrodialysis, alkali metal ions from an aqueous solution of the alkali metal salt of an AADA. By this configuration, an AADA salt can be produced in a much higher yield than conventional equivalents without requiring a regeneration operation of a resin as in the use of an ion exchange resin or without requiring crystallization-separation of crystals of the AADA salt as in the addition of an organic solvent. A salt of an amino acid-N,N-diacetic acid is also produced by reacting an AADA with any of metal oxides, metal hydroxides, metal carbonates, metal hydrogencarbonates, ammonium hydroxide, ammonium carbonate, ammonium hydrogencarbonate or organic amine compounds. By this configuration, a metal salt, ammonium salt or organic amine salt of an AADA can be produced with efficiency without the formation of by-products.
