dc.description.abstractTiO2 is extensively used as a photocatalyst due to the strong oxidizing power of its holes, high photostability and redox selectivity. The oxymetric method was investigated for testing of photocatalytic properties of TiO2 on dye acid orange II and a saccharide to observe the influence of oxygen concentration which decreases under UV radiation. The oxymetric method was modified to test cotton and polyester samples coated with TiO2 for photocatalysis and self-cleaning properties. The findings show that there is a linear correlation between the decrease of dissolved oxygen concentration as a function of time which shows photo catalytic behavior. The kinetic model is proposed for the degradation of acid orange II which resulted in slight decolourization of the dye acid orange II. Self-cleaning property tested on cotton samples stained with red wine and coffee and exposed to solar radiation for 1 day showed some decolourization of the stains.en
