Effluent Treatment of Synthetic Tanning by Nanomaterials Photocatalytic

Article Preview

Abstract:

The industry is one of the most polluting sectors of the aquatic ecosystem. Conventional treatment methods no longer have full effectiveness. The heterogeneous photocatalysis, using TiO2 as the semiconductor (photocatalyst) is one of the most promising techniques for polishing industrial effluents. In the present study determines the best pH range, to optimize the phenomenon of adsorption, and evaluates the reduction of hexavalent chromium and the removal of organic matter in synthetic samples, using a reactor with glass plate impregnated with TiO2 and making use of solar radiation. It was observed that the acidic pH is optimal for the photocatalytic process and that there was a minimum removal efficiency of 62% and 60% for Cr (VI) and organic matter, respectively.
