Modified uncrosslinked and crosslinked chitosan derivatives were investigated as green sorbents for the removal of copper (Cu 2+ ) and lead (Pb 2+ ) cations from simulated solutions. In this regard, N, O carboxymethyl chitosan (N, O CMC), chitosan beads (Cs-g-GA), chitosan crosslinked with glutaraldehyde/methylene bisacrylamide (Cs/GA/MBA), and chitosan crosslinked with GA/epichlorohydrin (Cs/GA/ECH) were prepared and characterized by Fourier transform infrared spectroscopy, X-ray diffraction, thermogravimetric analysis, and scanning electron microscopy analyses. Atomic force microscopy investigation was carried out to compare the surface topography of the prepared samples before and after the metal uptake. The kinetics of the removal process were investigated by pseudo-first-order and -second-order models. Moreover, the adsorption isotherms were carefully studied by applying Langmuir and Freundlich models. The data reveal that upon adsorption of copper(II) metal ions, all chitosan-modified products followed the Langmuir isotherm except for Cs/GA/ECH which followed the Freundlich isotherms, and the highest adsorption capacity ( q e ) was obtained for Cs/GA/MBA due to the formation of stable chelate structures between the metal cation and the functional groups present on the modified chitosan product. The order of metal uptake at the optimum pH value is as follows: Cs/GA/MBA (Cu: 95.7 mg/g, Pb: 99.15 mg/g), Cs/GA/ECH (Cu: 80.4 mg/g, Pb: 93.14 mg/g), Cs-g-GA (Cu: 77 mg/g, Pb: 88.4 mg/g), and N, O CMCh (Cu: 30.2 mg/g, Pb: 44.8 mg/g). The AFM data confirmed the metal uptake process by comparing the roughness and height measurements of the free sorbents and the metal-loaded sorbents.

“…Lately, a strong interest has also been addressed to the development of novel and more efficient composite biosorbents based on polysaccharides and inorganic fillers (clays, zeolites, GO, or magnetic nanoparticles) and on their application in the treatment of wastewater ( Table 5 ). This growing attention on organic/inorganic composite sorbents is associated with their advantages in the separation processes, such as their improved sorption capacity, fast kinetics, and remarkable mechanical and chemical stability during regeneration and reusability studies [ 19 , 133 , 134 , 135 , 136 ].…”

Nowadays, pollution has become the main bottleneck towards sustainable technological development due to its detrimental implications in human and ecosystem health. Removal of pollutants from the surrounding environment is a hot research area worldwide; diverse technologies and materials are being continuously developed. To this end, bio-based composite hydrogels as sorbents have received extensive attention in recent years because of advantages such as high adsorptive capacity, controllable mechanical properties, cost effectiveness, and potential for upscaling in continuous flow installations. In this review, we aim to provide an up-to-date analysis of the literature on recent accomplishments in the design of polysaccharide-based composite hydrogels for removal of heavy metal ions, dyes, and oxyanions from wastewater. The correlation between the constituent polysaccharides (chitosan, cellulose, alginate, starch, pectin, pullulan, xanthan, salecan, etc.), engineered composition (presence of other organic and/or inorganic components), and sorption conditions on the removal performance of addressed pollutants will be carefully scrutinized. Particular attention will be paid to the sustainability aspects in the selected studies, particularly to composite selectivity and reusability, as well as to their use in fixed-bed columns and real wastewater applications.

“…The adsorption capacity of the GO for V(IV) is more than 4 times that of calcium hydroxyapatite, [19] and also higher than that of carbon-based adsorbents for V(V), [22,37,38] although lower than that of the hydrogel material reported by Jana et al [18] The better performance of the hydrogel may be due to that the enhanced coordination between the hydrogel and V(IV) in near neutral condition is stronger than the force between GO and V(IV) at the low pH value. [39] Therefore, GO has a potential to adsorb V(IV) ions in acidic waste water.…”

Vanadium is a long-confined contaminant. In this study, graphene oxide (GO) was synthesized by the modified Hummers' method and used to remove vanadium(IV). The adsorption isotherms and kinetics of vanadium(IV) on GO at pH 2.5 and three temperatures are measured in batch experiments. The influences of ionic strength is investigated and the regeneration of GO is evaluated by washing with HCl. The results show that the adsorption isotherm corresponds to Temkin model with an adsorption capacity of 70.56 mg/g at 298 K, while the kinetic process coincides with pseudo-secondorder model and approaches to equilibrium in 6 h. The adsorption capacity of GO is not influenced by Na + ionic strength, but sharply inhibited by Ca 2 + . The superior adsorption is dominated by electrostatic interaction, coordination bonding, and hydrogen bonding. Moreover, the GO is reusable, as shown by maintaining 53.4 % of the initial efficacy after five sequential adsorption-desorption cycles.
