Title

DECOLORIZATION AND MINERALIZATION OF DIRECT BLUE86 BY UV/TIOO2 PROCESS: INVESTIGATIONS ON THE EFFECT OF OPERATIONAL PARAMETERS

Pages

  8-18

Abstract

 Direct Blue 86 (DB86), commonly used as a textile dye, can be degraded photocatalyticaly in aqueous solutions using TiO2 suspensions. A 400 W UV-A lamp was used in a batch circulating PHOTO-REACTOR, without any dead zone. An initial concentration of 50 mg/L of dye, as a typical concentration in textile wastewaters, was used and the influence of catalyst concentration, pH and temperature were investigated. The experiments showed that degradation of dye can be effectively occurring in the both branches of photolysis (only UV) and photocatalysis (UV/TiO2). Accordingly, the optimum operating conditions of: catalyst concentration: 40 mg/L, pH of 4 and temperature of 40oC were obtained. Under these conditions, a degradation of about 96% and a mineralization of about 87% (based on COD measurements) of dye were achievable during about only 120 min.
