| Abstract. In this study, the Fenton/adsorption of dye effluent containing Levafix blue dye has been performed using cost-efficient and ecologically friendly heterogeneous Fenton and solar-Fenton techniques. Alum sludge, the water treatment by-product were successfully collected and calcined to 400 °C (AS400) were tested for its potential application as a catalyst in the Fenton reaction. X-ray diffraction, Scanned electron microscopy techniques were applied to investigate the structural and morphological properties of such catalyst. The results showed that the material had a better photocatalytic activity under sunlight irradiation. The solar photo-Fenton method containing AS400 was shown to be competent for the oxidation of Levafix dye. The oxidation was improved to a great extent from 60 to 99% removal in the treatment time of 40-min irradiation. The key factor is containing 1.5 g/L and 800 mg/L of AS400 and H2O2, respectively, at pH 3.0. As a result, the practical application of such a by-product as a catalyst on the Fenton system employing natural solar radiation on the treating dye effluent indicates that technique is extremely efficient for a safer environment. |
