Abstract

Abstract: This work involved the removal of textile dyes by synthesized Ni-Fe-SDS and Ni-Fe-SO4 layered double hydroxides (LDH). The adsorbent was synthesized using co-precipitation method at room temperature. Samples were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy with energy dispersive X-ray spectroscopy (SEM-EDX) and inductively coupled plasma (ICP). The obtained materials were used for the removal of methyl orange (MO) as a model anionic dye. Adsorption experiments were carried out under different solution pH and contact time. XRD analyses indicate low degree of crystallinity when using SDS as an intercalating anion in the LDH structure. Experimental results indicate rapid adsorption process with maximum adsorption capacity occurred in acidic medium. The maximum adsorption capacities were 105.36 and 82.45 mg/g, respectively for Ni-Fe-SDS and Ni-Fe-SO4 samples.
