- W2891396060 abstract "Abstract Carbon nanostructured materials have been recognized as perspective adsorbents for removal of toxic anions of hexavalent metals M(VI) from surrounding media. The article reveals the peculiarities of such removal mechanisms at a single‐molecule level. Adsorption of M VI O 4 2− (M VI = Cr, Mo, W), Cr 2 O 7 2− , and HCrO 4 − anions on the surface of pristine, B(N)‐doped, and functionalized by functional groups (COOH, COO − , OH, and NH 3 + ) carbon nanotubes (CNT) and graphene is studied in the density functional theory electronic structure calculations carried out in vacuo and in aqua using polarizable continuum model. It is found that neither pristine, nor B or N‐doped CNTs can be efficient adsorbents of the anions in water. Functionalization of the CNT‐based materials with oxygen‐ or ammonia‐containing surface groups will allow creation of efficient adsorbents of Cr(VI) toxic anions at low pH levels of water solution. Whereas at high pH (> 6), only functionalization by ammonia‐containing groups is feasible for this task." @default.
