Photo-catalytic reduction of chromium in aqueous solution by Fe<sup>3+</sup> doped TiO<sub>2</sub> nanoparticles
513-515The 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
