标准范围
This International Standard specifies a method for the determination of the photocatalytic activity of surfacesby degradation of the dye molecule methylene blue (MB) in aqueous solution using artificial ultraviolet (UV)radiation, and characterizes the ability of photoactive surfaces to degrade dissolved organic molecules onultraviolet radiation.The test method specified is also applicable to evaluation of the specific photocatalytic self-cleaning activity ofsurfaces covered with respective coatings.This method is not applicable to characterizing the photoactivity of surfaces on visible illumination, regardingdirect soiling, degradation of gaseous molecules and the determination of antimicrobial photoactivity ofsurfaces.NOTE Correlations between these different kinds of photocatalytic activity can, however, exist, in particular atsurfaces exhibiting low photonic efficiencies.
