fe-cu binary oxides as low-cost adsorbents and their application in photocatalytic removal of acid red 14, methyl orange and malachite green from aqueous solutions

Abstract:in this work, a series of binary oxides with 0:1, 1:10, 1:7, 1:5, and 1:0 cu:fe molar ratios were synthesized by a simple, low cost and effective procedure. the anionic dyes namely, acid red 14 (ar14) and methyl orange (mo) and malachite green (mg) as a cationic dye removal and adsorption onto these materials was investigated. the effects of cu:fe molar ratio, ph, and sorbent dosage were investigated at 25±1 °c. the synthesized adsorbent compound containing 1:7 molar ratio of cu:fe verified to possess an uppermost dye adsorption capacity. subsequently, this new sorbent was characterized using different techniques such as fourier transform infrared spectroscopy (ft-ir), x-ray powder diffraction (xrd), scanning electron microscopy (sem), transmission electron microscopy(tem), and energy-dispersive x-ray spectroscopy (edx). the new nanostructure was confirmed for dye adsorption in the presence of uv irradiation. selected fe-cu binary oxide exposed the highest adsorption capacities of mg regarding the other dyes. it would be a practical process of removing mg from aqueous solution by increasing adsorption efficacy during wastewater treatment. the photocatalytic performance of as-fabricated binary oxides was surveyed with the destruction of dye.
