Photocatalytic degradation study of Methyl Orange and Congo red using Mg-Co ferrite powder

The photocatalytic degradation of methyl orange and Congo red dye was performed under the illumination of visible light (Philips ۲۵۰Watt) as a source of photons. The complete distraction of the aromatic ring was ascertained by UV spectroscopic analysis. A decrease in dye concentration and an increase in the concentration of CO۲ indicate dye mineralization. The behavior of this reaction was pseudo-first-order and the maximum photodecolorization efficiency was ~۸۵.۱۶% for Methyl orange and ~ ۹۵.۴۰ for Congo red in ۱۲۰-۱۵۰ min. at ۳۰oC.
