Fine ceramics (advanced ceramics, advanced technical ceramics). Determination of photocatalytic activity of surfaces in an aqueous medium by degradation of methylene blue Ingestion-build-279162 structuring and compilation of information1 Scope This International Standard specifies a method for the determination of the photocatalytic activity of surfaces by 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 on ultraviolet radiation. The test method specified is also applicable to evaluation of the specific photocatalytic self
