Abstract

Textile industrial effluents, which are mostly dyes, are one of the main sources of pollutants in water systems. One of the emerging technologies in degrading dyes in textile wastewater is photocatalyst. Batch photocatalytic experiments were carried out in a reactor in order to asses the main and interaction effects of six parameters (Temperature, Catalyst Loading, Initial Dye Concentration, Irradiation Time, pH and Source of Light) and also the most influential factor in the decolorization of Direct Congo Red dye solution using a 2ᵏ full factorial design. The experimental matrix was conducted under two conditions: one in UV light and the other in White light. In order to increase the reliability, the runs were done i two trials and the highest result was 85.71% decolorization. The results were evaluated using Multiple-way Analysis of Variance (MANOVA), Effects Plots, Pareto Chart and Normal Probability Plots. Separate analyses were done on the experiments that were carried out in UV light and White light. Results showed that at 95% confidence level, all the main effects and some of their interaction effects on both conditions are significant. Regression models for the UV light and White light were suggested and fitted the experimental data adequately well.
