Abstract
A process for the decomposition of photocatalytically decomposable organic material includes exposing the organic material to ultraviolet light as the material is passed across the surface of a spinning disc. The organic material is in the form of a liquid dispersion, preferably an aqueous dispersion and the dispersion also contains anatase titanium dioxide which acts as a catalyst in the decomposition process. Preferably the anatase titanium dioxide has a high surface area. Organic materials such as hydrocarbons, alcohols, acids, esters and others are destroyed in this environmentally acceptable process.
