Abstract
A method for purifying water containing pollutant mixtures is described, which uses a reactor containing a semiconductor as reaction catalyst and a lamp which emits radiation having a wavelength of less than 400 nm. The reactor, characterized in that its walls allow water and the pollutant substances to pass through, is immersed in the water to be purified so that the pollutants contained in it reach the reactor interior where they are adsorbed on the semiconductor activated by light radiation, and are then degraded.
