Document Type and Number:
WIPO Patent Application WO/2003/061862
Kind Code:
A1
Abstract:
A method and apparatus in which a pollutant present in a relatively low concentration is treated by photocatalysis without via the concentration step which has been conventionally necessary for obtaining a pollutant concentrate to be treated by decomposition by photocatalysis. The method for pollutant removal is characterized by comprising: a step in which a pollutant is absorbed in and/or adsorbed onto an absorbent having a photocatalyst material; and a step in which the absorbent having the pollutant absorbed and/or adsorbed is exposed to sunlight to decompose the pollutant by photocatalysis.
