Nano-silica from white silica sand functionalized with PANI-SDS (SiO/PANI-SDS) as an adsorbent for the elimination of methylene blue from aqueous media.

Natural resources including sand are one of the best approaches for treating dye-polluted wastewater. The SiO/PANI-SDS nanocomposite was synthesized by self-assembly and intermolecular interaction. The physicochemical features of the SiO/PANI-SDS nanocomposite were explored by FT-IR, XRD, SEM, TEM, EDX, and N adsorption-desorption techniques to be evaluated as an adsorbent for the MB.
