Abstract
The efficiency of polyaniline/Fe 3 O 4 (PANI/Fe 3 O 4 ) nanocomposite (NC) as an adsorbent was investigated in the removal of Titan yellow (TY) dye from aqueous solution. The PANI/Fe 3 O 4 was synthesized by polymerization of aniline in H 2 SO 4 medium in the presence of Fe 3 O 4 nanoparticles with ammonium persulfate as an oxidant. The NC formed was characterized by SEM and FT-IR methods. The dye removal process was studied under various conditions and was found that the adsorption activity of the PANI/Fe 3 O 4 NC was greater than that of the bare PANI and Fe 3 O 4 nanoparticles. Adsorption kinetics fitted with pseudo-first-order kinetic model.
