A great challenge for this century lies in cleaning up the waste generated during industrial, do-mestic and agricultural activities. Water, an essential fluid on which all life depends, is heavily affected by such activities.Among the various contaminants found in water, heavy metals require special attention because of their toxic effect on humans and the environment, even at very dilute concentrations. Here, we report the synthesis of PANI/G composite containing graphene sheets (G), and polyaniline (PANI) via chemical route for removal of toxic Cr (VI) from water. TEM image shows the formation of uniformly distributed graphene/PANI composite. The functionalization of graphene sheets with polyaniline (PANI) was carried out in the aqueous medium via polymerizing aniline in the presence of graphene oxide and reducing it with sodium borohydride. The Cr(VI) removal capacity increases with graphene oxide loading and shows maximum for 12% loading (PANI-G12). The time dependent adsorption data shows maximum adsorption at 50min onto PANI-G12.
