Removal of p-Nitrophenol from Aqueous Solution Using Synthesized Silica-Magnetite Composite
Silica-magnetite composite was synthesized as model adsorbent for the removal of p-nitrophenol (p-NP), a problematic toxicant present in effluents from pharmaceutical and allied industries. The adsorption behavior was studied by batch method. Prepared adsorbent was fully characterized using Fourier...
