Abstract

Iron based heterogeneous catalysts are widely used in many industrial applications including Fenton Oxidation Processes (FOPs) to treat the effluents containing recalcitrant contaminants such as dyes. In this work, Metal-Organic Framework (MOF) derived iron nano oxide particles supported on ZSM-5 zeolite were synthesized under optimized experimental conditions. The Central Composite Design (CCD) method was employed to optimize the yield of the catalyst. The catalyst was then characterized using EDX, SEM, HRTEM, FTIR, STA and BET. Subsequently, the catalytic activity of the catalyst in the Fenton oxidation process was evaluated based on the degradation of the model azo dyes Acid Blue 113, Methyl Orange, and Reactive Black. The optimized experimental yield was 81.5%, which was in agreement with the CCD prediction. Apart from high catalyst yield, excellent mineralization efficiency was obtained where 77%, 71% and 68% of Total Organic Carbon (TOC) removal were achieved for Acid Blue 113, Methyl Orange, and Reactive Black 5, respectively. Based on the yield and activity, it was concluded that the synthesized Fe-ZSM-5 is a promising catalyst for the Fenton oxidation process.
