چکیده	One of the suitable methods for removing heavy metals from aqueous solution is using surface adsorption process. In this article, the effect of polyaniline (PAn) and its nanocomposite and also, the influence of pH of solution on the removal of lead cation from aqueous solution were studied. The polyaniline nanocomposite was prepared using poly(vinyl alcohol) (PVA) as surfactant in the presence of ammonium peroxy disulfate ((NH4)2S2O8) as an oxidant. The results indicate that the removal of lead in aqueous solution (pH = 7) were 88.2 and 94%, when polyaniline and polyaniline/PVA nanocomposite were used as adsorbents respectively. Also, the results show that removal percentage increases in alkaline solution. The structure of obtained product was determined by FTIR spectroscopy.
