Methyl Orange removal from aqueous solutions with a novel super magnetic iron oxide nanocomposite hydrogel

This paper considers the extraction and determination of methyl orange from aqueous solution. Batch solid phase micro extraction was applied for this purpose. A novel super magnetic iron oxide nanocomposite hydrogel was prepared, characterized and selected as an adsorbent. Various methods such as Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy with energy dispersive X-ray analysis (SEM–EDAX), transmission electron microscopy (TEM), thermal gravimetric analysis (TGA) and X-ray diffraction (XRD) were used for characterizing the prepared adsorbent. Some important factors which control the adsorption capacity were examined therefore the optimal value were selected
