Abstract

Photo catalytic processes in the presence of titanium dioxide provide an interesting route to destroy hazardous organic contaminants, being operational in the UV-A domain with a potential use of solar radiation. The solar photo catalytic degradation of paper mill wastewater has been studied over synthesized nano TIO₂. The catalyst was characterized by techniques like x-ray diffraction (XRD).. The enhanced photo catalytic activity of the synthesized catalyst is attributed to the crystalinity, nano size, large amount of surface hydroxyl species and reduced band-gap.
