Abstract
A purifier for water or air removes, reduces or detoxifies organic pollutants therefrom by causing the fluid to contact a matrix having surfaces with which a fixed anatase (TiO.sub.2) or other photoreactive metal semiconductor material is bonded, in the presence of light of a wavelength that will activate the material.
Claims8
A matrix for use in a method of removing, reducing or detoxifying organic pollutants from a fluid, comprising a substrate in the form of a plurality of layers of a filamentous, fibrous or stranded base material, and a photoreactive metal semiconductor material bonded with, to or into surfaces of said layers, at least one of said layers being at least partially transparent to light at a wavelength to which the semiconductor material photoreacts.
