Addition of various organic and inorganic pollutants reduces clean water sources day by day. Among other impurities, organic dyes are typical toxins that should be removed from drinking and wastewater. Adsorption is the simple, low cost and one of the most commonly used technique to remove these dyes. Metal Organic Frameworks (MOFs) have appeared as a new type of adsorbent materials, gained rapid development and fast escalation over the past twenty years. In this work, three different MOF materials were successfully synthesized at room temperature by using Nickel, Cobalt & Magnesium Nitrate Hexahydrates as inorganic precursors and Oxalic Acid as an organic linker. These MOFs was applied to the adsorption of three organic dyes namely, Methylene Blue (MB), Methyl Orange (MO) and Methyl Red (MR) from aqueous solution. Characterization of these lab prepared MOFs were achieved by XRD, SEM micrographs, FT-IR spectra and TGA analysis. The possible mechanism and the adsorption behavior of the adsorption of three organic dyes onto Nickel Oxalic Acid (Ni-Ox), Cobalt Oxalic Acid (Co-Ox) and Magnesium Oxalic Acid (Mg-Ox) MOFs were investigated by using UV-Spectroscopy. The experimental results recommended that among these MOF materials Ni-Ox adsorbent material have potential application for the degradation of organic pollutants from aqueous solution.
