Quick removal of dye from water and waste water is very important in the research related to eliminating pollutions; this is because of the spread of damaging effects of dyes in water on the human beings and the environment. Four different carbon nanostructures, namely graphene oxide, oxidized multiwalled carbon nanotubes, activated carbon, and multiwalled carbon nanotubes were applied as adsorbents for the removal of Indigo Carmin (IC) dye from aqueous solution.
