China Environmental Science, 2005,25(Suppl.)26~29 Abstract Aqueous dispersion of nano-titanium dioxide (TiO ) was prepared and the nano-TiO was loaded on the surface 2 2 of cotton fabric adopting after arrangement method to form nano-TiO2 loaded fabric possessing photo-catalytic character, and was characterized using X-ray diffraction (XRD) and scanning electron microscope (SEM). The photo-catalytic purification of ammonia released from the concrete in the simulated chamber was studied utilizing the self-designed photo catalytic reactor. The influence and action of the factors (including dosage of aqueous dispersion of nano-TiO2, dye, and type of fiber) on the property of purification were inspected respectively. Under the irradiation UV light at the wavelength of 365nm, the prepared cellulose fabric loading nano-TiO had good purification actio
