摘要：
The invention relates to a method for photocatalytically precipitating a dispersed material from a tenside dispersion. The tenside dispersion comprises at least one dispersing agent, a dispersed material, a tenside, and a photocatalyst. Titanium dioxide is in particular suitable as a photocatalyst that is photoactive in the ultraviolet range and optionally also in the visible spectral range. The dispersing agent is preferably water or an aqueous fluid. Perfluoridated tensides (PFT), among others, are also suitable as a tenside. The method is characterized in that in particular temperature-sensitive materials, such as polytetrafluorethylene (PTFE) can be precipitated in a simple manner.
