Abstract
A process for the decomposition of photocatically degradable organic material includes exposing the organic material to ultraviolet light as the material is passing across the surface of a spinning disc. The surface of the disc carries anatase titanium dioxide adhering to the disc. The anatase titanium dioxide acts as a catalyst in the degradation process and preferably has a high surface area. Organic materials such as hydrocarbons alcohols, acids, esters and others are destroyed by this environmentally acceptable process.
