Application of efficient photocatalytic process using Fe۳O۴/Mn/Graphite composite for removal of Alizarin dye by response surface methodology

The aim of the present study was to investigate the photocatalytic properties of Fe۳O۴/Mn/Graphite composite for the removal of Alizarin from aqueous solutions. The experimental results revealed that the prepared Fe۳O۴/Mn/Graphite composite had higher photocatalytic performance for Alizarin removal. However, the optimization of the experiments was performed using response surface methodology (RSM) that designed by Expert Design software. At the optimum conditions, the maximum Alizarin removal efficiency was reached to ۸۹.۹۱% at initial dye concentration: ۸ mg/L, initial pH: ۸, reaction time: ۴۰ min and Fe۳O۴/Mn/Graphite dosage= ۰.۰۳ mg/۵۰ ml. Thus, this novel Fe۳O۴/Mn/Graphite composite could be used as an effective photocatalyst to remove of Alizarin dye from aqueous solutions.
