The problem of disposal of toxic waste is serious but the methods currently available are either complex and expensive or may result in generation of some other unwanted material during the disposal. There is a great need for economical and simple methods for disposal and degradation of both organics and inorganics. In our work we have utilized colloidal titania sol prepared by extremely simple means and use them for degradation of various organic compounds. In this presentation we will discuss the property of the “TRANSPARENT” titania sols that we have prepared using Titanium tetrachloride in our lab, and how they have been utilized to photocatalytically degrade MTBE and nitrophenol. MTBE is an extremely persistent pollutant because it is extremely stable to degrade while nitrophenol is a very widely used pollutant. We will describe conditions and parameters that we have used and discuss the results that we have obtained to show the successful degradation of these important pollutants
