Description 474-479
In this investigation, decolorization of a direct dye solution catalysed by TiO<sub>2</sub> coated on a cotton fabric by sol- gel route in presence of UV radiation has been studied. Effect of various process and material parameters like initial dye solution concentration, treatment time and temperature, stirring rate and construction of fabric on dye decolorization extent has been studied. It is observed that with a starting dye solution concentration of 0.1 g/L, almost 80% dye removal can be achieved. It is not possible to improve the decolorization extent beyond 80% by any combination of parameters. X-ray diffraction studies reveal that the form of TiO<sub>2 </sub> deposited on cotton fabric is not crystalline but amorphous in nature. While the UV radiation intensity and the fabric construction influence the dye decolorization, the treatment temperature and stirring rate do not have much bearing on decolorizing efficiency.
