[origin: DE19928047A1] Use of pollutant-deficient to pollutant-rich aqueous systems for the galvanic deposition of precious metals and precious metal alloys is new. The pollutant-deficient to pollutant-rich aqueous systems contain gold and/or silver in the form of water-soluble protein amino acid derivative, a water-soluble sulfonic acid, a waster-soluble nitro compound, a water-soluble nitrogen compound, a water-soluble commercial tenside, a water-soluble sulfone derivative, and optionally an alloying metal.
