摘要：

Photocatalytic degradation of two commercial dyes, Methylene Blue and Reactive Orange 4, in aqueous phase by mill scale (solid waste generated in steel plants) using advanced oxidation process was studied. The effects of various factors on the extent of degradation were investigated. These included: (1) the catalyst quantity, in the range 0.1-1.3 g/100 mL; (2) Methylene Blue concentration in the range 0.01-0.1 mM/100 mL; (3) Reactive Orange 4 concentration in the range 0.05-0.25 mM/100 mL; and (4) the concentration of hydrogen peroxide in the range 1-4/100 mL for Methylene Blue and 1-2/100 mL for Reactive Orange 4. The optimum catalyst dose in presence of hydrogen peroxide and UV illumination was found to be 0.8 and 0.3 g/100 mL for Methylene Blue and Reactive Orange 4, respectively. The decomposition rate was found to decrease with increasing dye concentration and increase with increasing hydrogen peroxide concentration. © 2015 Springer International Publishing Switzerland.
