Abstract
In this study, polypyrrole (PPy), polyaniline (PANi) and poly 3-methyl thiophene (P3MTh) conducting polymers were synthesized chemically as coated on the surface of wood sawdust (SD), then used for removal of arsenic ions (As3+) from aqueous solutions. The experiments were performed using both batch and column systems. In order to find out the possibility of desorption for frequent application, the chemical regeneration of the used column was also investigated
