  • Method for Photocatalytic Separation from Surfactant-Containing Dispersions
    Publication number: 20100224480
    Abstract: The invention relates to a method for photocatalytic separation of a dispersed substance from a surfactant-containing dispersion. The surfactant-containing dispersion contains at least one dispersant, one dispersed substance, one surfactant and one photocatalyst. Irradiation of the photocalyst causes the decomposition or modification of the surfactant allowing for the separation of the dispersed substance from the dispersant.
