Photocatalytic treatment of water contaminated by organic dye with ETS-10 titanium silicate

Abstract

Abstract In this research, ETS-10 titanium silicate (Engelhard titanium silicate) was studied for the treatment of water contaminated by the organic dye called Blu Patent V, which is commonly used in the textile industries. In addition to being a microporous material, the ETS-10 phase also has photocatalytic capacities. In particular, predetermined quantities of ETS-10 have been added to the Blu Patent V solutions and the entire system has been exposed, for programmed times, to sunlight. Systems also in the presence of hydrogen peroxide were used. The resulting solutions were analyzed with UV spectrophotometry to evaluate the reduction of the dye. ETS-10, after treatment, was analyzed by thermogravimetric analysis (TG).
