|Abstract:||The present study deals with the photo-catalytic reduction of Cr (VI) by TiO2 nanoparticles. A detailed adsorption study of Cr (VI) by Fe3+ doped TiO2 at different pH shows that the adsorption of chromium by TiO2 nanoparticles is governed by charge of TiO2 nanoparticles. which depends on the pH of solution. Kinetic studies show that reduction and adsorption of Cr (VI) by Fe3+ doped TiO2 are not similar. Photocatalytic reduction of Cr (VI) by Fe3+ doped TiO2 is more feasible at low pH. Fe3+ doped TiO2 nanoparticles accelerate the reduction rate of Cr (VI) to Cr (III) than commercially available TiO2 particles.|
