  • Patent number: 4172775
    Abstract: Mixtures of metals are separated by forming salts of the metals which exhibit photoredox activity with an anion selected to provide insoluble salts at one oxidation state and soluble salts at another oxidation state, forming a solution of these salts with a solvent selected to permit a difference in solubility of salts dissolved at different oxidation salts and to be nonreactive with the nonsoluble salts, irradiating the solution with light at a wavelength which changes the oxidation state of the metal ion most susceptive to a change in oxidation state, and separating the insoluble salt formed thereby from the solution.
