Abstract

Backgrounds and Aim: The textile industries daily discharge millions of liters of coloredeffluent into the environment. These effluents are usually non-biodegradable and pose aserious problem to human and aquatic living organism. So, the aim of this study was toevaluate the degradation of Direct Blue71 using Ba: TiO2 nanocomposite as a catalyst in thepresence of SUNLIGHT. Material and Methods: This study was an applied research in which Ba: TiO2nanocomposite was synthesized and also The effects of parameters on the photocatalysisprocess such as initial DYE concentration, PHOTOCATALYST dose and pH were also studied. Results: The results of the study showed that the DYE degradation decreased with increasingthe DYE concentration and nanocomposite dose. It is observed that DYE degradation can befavored by lowering the pH of solution and the photocatalysis degradation rate of DYEincreases with decreasing solution pH, because under acidic pH, hydroxyl radical is thepredominant reactive oxidant. It was also found that the photocatalysis degradation followedthe Langmuir-Hinshelwood kinetic. Conclusion: It is concluded that the synthesized NANOPARTICLE has a high potential for DYEdegradation in comparison with pure TiO2 and can be used as an effectivephotocatalyst for degradation of DYEs form colored effluents.
