Abstract: Various conducting polymers have emerged as a new dimension of adsorbing materials for removing the heavy metal ions from waste water or aqueous solution. In this study, a novel conducting polypyrrole (Ppy) fine powder has been prepared as a new adsorbent for the removal of heavy metal ions like arsenic ions from aqueous solution. Polypyrrole was chemically synthesized by using FeCl3.6H2O as an oxidant at various mole ratios. Various ion concentrations of arsenic were treated by Ppy adsorbent and the concentrations of arsenic were measured by inductively coupled plasma mass spectroscopy (ICP-MS). The efficiency of the adsorbent was evaluated by calculating the difference of arsenic concentrations before and after adsorption. The results show that Ppy acts as an effective adsorbent for the removal of arsenic ions from aqueous solution. The surface morphology and functional groups of the adsorbents were analyzed by Field Emission Scanning Electron Microscopy (FE-SEM) and Attenuated Total Reflectance Fourier transform infrared (ATR-FTIR) spectroscopy, respectively, before and after treatment.
