Facile Synthesis of Nanosized MgO as Adsorbent for Removal of Congored Dye from Wastewate

Nanostructures of magnesium oxide is one of the most attractive materials which have shown various applications in many aspects of industries. So, finding a controllable and inexpensive technique to produce desirable nanostructures of MgO is valuable. In this work, magnesium oxide (MgO) with different morphologies was successfully prepared via a simple solid-state method. The molar ratio of sodium hydroxide to magnesium salt precursor was obtained 1 to 8. Furthermore, the effect of different magnesium precursors (magnesium chloride and magnesium acetate) on the morphology of MgO was investigated. It was shown that adding halide salts (NaX) to the solid-state reaction media, in spite of the noteworthy influence on the product morphology, facilitate the formation of MgO phase from Mg(OH)2. The synthesized magnesium oxide particles were characterized by Fourier transform infrared (FTIR) spectrometer, scanning electron microscope (SEM) and X-ray diffraction (XRD). Synthesized magnesium oxide particles were used to remove congored dye from waste water.
