Degradación de fenoles presentes en las descargas de aguas residuales de la Refineria de Shushufindi mediante fotodegradación utilizando óxido de titanio (IV) adherido electroquímicamente para su descontaminación, 2016.

Abstract

The presence of phenols in industrial waters, establish a problem in its final moment. The present work aimed at the degradation of fungi in the wastewater discharges of the Shushufindi refinery by photo catalytic degradation. By the method of catalytic electrophotographic degradation , which is bound in the electrochemical adhesion of titanium oxide IV (TiO 2 / UV) , the degradation of the phenols in the waste water was carried out indicating a high efficiency of 99% in a lapse of 180 minutes ; In an acid medium of 5,14 and UV-Visible lamp ( Vilber Lourmat 1102600; λ = 365 nm ). Demonstrating a transformation in hydrophilic radicals from water performing the comparative treatments Fenton (H xvi

2 O 2 / Fe 2+ ) and electro-catalytic photo, the degree of efficiency was determined. By means of phenol concentrations of 30, 50 mg/L the percentages of degradation of 98 to 99 % of the contaminant were obtained. It was concluded that the TiO 2 / UV electro-photo degradation method, in the acceleration of the degradation, was more efficient, having more favorable advantages that the treatment Fenton (H 2 O 2 / Fe 2+ ), reducing the costs in reagents, pieces of iron in water that can cause health problems. It is recommended to use the catalytic electro-photo degradation method for the treatment of industrial waters.
