ABSTRACT

The aim of the study was to investigate the photocatalytic efficiency of mill scale (waste iron oxide collected from local steel plants) for the degradation of textile dyes. The photodegradation on methylene blue (MB) in natural environment with co-existence of mill scale and oxalic acid/ H₂O₂ under UV or sunlight were studied. Some effecting factors such as mill scale content, oxalate ion, H₂O₂ and MB concentration were also investigated. Dye decomposition rate was found to increase with an increase in the amount of mill, reached a maximum and then decreased with increasing mill scale concentration. The decomposition rate decreased with increasing dye concentration. Faster dye degradation was observed by mill scale/H₂O₂ than with mill scale/oxalic acid system. Photocatalytic performance of mill scale (a solid waste) was found as an interesting alternative for the degradation of dyes (liquid waste).
