“…Carbonaceous nanomaterials. Adsorption of heavy metals by C-ENMs has been reported in several studies [8,32,[405][406][407][408]. Metal adsorption capacities of pristine CNTs is quite low, but may be significantly improved by functionalization [409][410][411].…”

2014): Adsorption properties for heavy metal ions from aqueous solution of the novel chelating resin loaded quaternary ammonium salt, Desalination and Water Treatment,The novel Schiff bases chelating resin loaded quaternary ammonium salt (CPS-QA-SBGL) had been synthesized with the cross-linked Polystyrene-Dimethylamine porous beads (CPS-DMA) as raw materials, which were bonded with glycine on the surface via a quaternary ammonium unit as a linker. CPS-QA-SBGL had been characterized by elemental analysis, infrared spectra and thermo-gravimetric analysis (TGA)-differential scanning calorimetry (DSC) analysis. Factors influencing the uptake of heavy metal ions such as pH, initial metal ion concentrations, shaking time and temperature were investigated systematically by batch experiments. The adsorption equilibrium study exhibited that heavy metal ions adsorption of CPS-QA-SBGL followed a Langmuir isotherm model better than a Freundlich model. The optimum adsorption conditions at 298 K were obtained: the initial concentrations of Pb 2+ , Cd 2+ , Cu 2+ and Cr 3+ were 600 mg/L, pH 5, the equilibrium adsorption uptake time was in 30 min. The kinetic data of adsorption of heavy metal ions on CPS-QA-SBGL were best described by a pseudo-second-order equation, indicating their chemical adsorption process. In addition, dynamic parameters suggest that adsorption of heavy metal ions onto CPS-QA-SBGL is involving an exothermic reaction and occurs spontaneously (△G <0).

“…Some of these processes are proved to be unacceptable owing to their low efficiency, high cost, disposal of sludge and sometimes inapplicability to a wide range of pollutants in the environment. Among these methods, adsorption is demonstrated to be an economical, efficient and promising technology for metal ions removal and widely used because of its low cost, high adsorption efficiency for low concentration metal ions [9][10][11]. There are various adsorbents, such as zeolites, silica, biomass, clays, active carbons and polymers, etc.…”
