Synthesis of polyaniline nanocomposite for the removal of Fe( II

In this research, Conductive polyaniline (PAn) and its nanocomposite was synthesized by in-situ polymerization in the presence of hydroxypropylcellulose (HPC) and poly(vinyl alcohol) (PVA) as surfactant and ammonium persulfate (APS) as an oxidant. The ability of polyaniline (PAn) nanocomposite to remove Fe(II) from aqueous solution was investigated in batch experiment for the treatment of diluted aqueous solution. In this respect, batch experiment was carried out at the pH range 3-12 and amount of dosage 0.1-1 g. The equilibrium data was better fitted with Langmuir model (r2= 0.992) than Freundlich model (r2= 0.460). The nanocomposite was synthesized under different experimental conditions and characterized by fourier transform infrared (FTIR) spectroscopy and scanning electron microscopy (SEM) like analytical tools. Batch adsorption results showed that the sorbent had high affinity to Fe(II) in aqueous solution.
