Degradation Kinetic of an organic dye promoted by titanium dioxide nanoparticles at various buffer pHs

A routine and simple decolorization pathway of pollutants is photocatalytic treatment of it inthe presence of photocatalyst that the generation of hydroxyl radicals in the photo-irradiatedmedium is responsible to elimination of pollutant [1-4]. Aniline Blue (AB) is harmful ifswallowed and may be harmful by inhalation or through skin contact. In this work we willreport photocatalytic decolorization of AB on nano-structure titanium dioxide at acidic,neutral and basic buffer aqueous solution. The kinetic study of decolorization of AB in eachbuffer pH is presented.
