“…Another study investigated the uranyl binding to a –COO functionalized CNT [38]. An experimental study of uranyl adsorption from aqueous solution utilized amine functionalized CNTs [39], while Atieh et al used oxidized CNTs as Pb complexants in their study of Pb removal from water [40]. The functionalization for ion selectivity or desalination phenomena were further exploited with oxidized CNTs [41, 42] and amino-doped graphene membranes [43, 44].…”

An explicit water molecular dynamics simulations were used to probe (6,6) and (9,9) single-walled carbon nanotubes, functionalized with three carboxylate ion groups at each of the two openings, as potential nanocarriers in aqueous solutions. Three tetraalkylammonium cations (i.e., tetraethyl-, tetrapropyl-, and tetrabuthylammonium) were tested as corks to cap the nanotube openings. The variation of the sizes of the nanotubes (diameter) and of the cork cations (bulkiness) allowed us to select the proper corks that fit the nanotube openings best. Smaller tetraalkylammonium ions could easily fit the openings, but since they are less hydrophobic compared to their larger analogues they showed less affinity for the interior of the nanotubes. On the other hand, the hydrophobicity (and thus the affinity for the nanotubes) can be adjusted through the increase of tetraalkylammonium cation size, providing that the cork still fits the opening. Additionally, an external electric field was tested as a means of nanotube uncorking. The field is capable of disjoining corked ions from the functionalized nanotube openings, triggering in this way a potential cargo release stored inside the nanotubes.

Poly(amidoamine) dendrimer functionalized carbon nano tubes were synthesized, characterized and used for the sorption of americium from aqueous acidic waste solution. The sorption of Am3+ has been found to take place through pseudo second order kinetics with the rate constants of 8.61E‐05 and 5.38E‐05 mg g−1 min−1for 1st and 2nd generation, respectively, followingLangmuir isotherm. The MWCNT‐PAMAMG1 and MWCNT‐PAMAMG2 have high radiolytic stability. The stripping study revealed that EDTA can be effectively used for almost quantitative back extraction of metal ion from both generation of dendrimer. Luminescence investigation revealed the presence of single species with no inner sphere water molecule. The 1st generation dendrimer complex was found to be more asymmetric compared to the 2nd generation. The analysis of Judd Offelt parameters and evaluation of photo‐physical properties were carried out to understand the complexation of Am3+ with these sorbents.
