The literature on adsorption of heavy metals such thallium (Tl), tellurium (Te), mercury (Hg), cadmium (Cd) and lead (Pb) using carbon based adsorbents such as activated carbon (AC), carbon nanotubes (CNTs), carbon nanofibers (CNFs) and carbon composites has been reviewed. The adsorption capacities for the above mentioned by AC, CNFs, CNTs and carbon composites operated under different conditions are
