Abstract

Treatment of textile wastewater is challenging because the water contains toxic compounds that have low biodegradability. This study discusses the textile dying effluent treatment by chemical oxidation technique which is experimentally optimized for treatment of industrial effluents. The disappearance of Basic yellow 28 from the effluent has been performed using Fenton’s reagent (Fe²⁺ and H₂O₂). The effects of different reaction parameters such as initial pH, the initial hydrogen peroxide concentration ([H₂O₂]₀), the initial ferrous concentration ([Fe²⁺]₀), the initial Basic yellow 28 concentration ([dye]₀) and the temperature on the disappearance of Basic yellow 28 have been assessed. The optimal reaction conditions were found to be; initial pH = 3.00, [H₂O₂]₀ = 0.20 mM, [Fe²⁺]₀ = 0.14 mM for [dye]₀= 0.04 mM at 25 °C. Under optimal conditions, 94 % disappearance efficiency of dye from aqueous solution was achieved after 120 min of reaction. The changes and percentage of color, chemical oxygen demand (COD), biological oxygen demand (BOD) were determined. The results showed that color was removed effectively in the aqueous solution. Under these conditions the percentage of color and COD removal efficiencies were reached 91, while for BOD removals the percentage reached 94.
