“…These levels are consistent with many data reported in the literature (Keshtkar et al, 2013;Liu et al, 2020a;Ma et al, 2020). This performance is much better than for other supports, where the loss in sorption reached up to 20% at the fifth cycle for functionalized porous activated carbon fibres (Mishra et al, 2015), or 15% for functionalized marine fungal biosorbent (Han et al, 2020). This means that the sorption is stable despite the changes observed in FTIR spectra; these chemical modifications (probably associated with protonation of some reactive groups) are not inhibiting the reactivity of functional groups at the surface of silica beads.…”

“…Tri-amidoxime modified marine fungus material had a uranium biosorption capacity of 584.60 mg/g with good regeneration performance. The unmodified biomass originally had a capacity of only 15.46 mg/g [108]. The macroporous ion-imprinted chitosan foams showed an adsorption capacity of 248.9-253.6 mg/g.…”

Biosorption is a variant of sorption techniques in which the sorbent is a material of biological origin. This technique is considered to be low cost and environmentally friendly, and it can be used to remove pollutants from aqueous solutions. The objective of this review is to report on the most significant recent works and most recent advances that have occurred in the last couple of years (2019–2020) in the field of biosorption. Biosorption of metals and organic compounds (dyes, antibiotics and other emerging contaminants) is considered in this review. In addition, the use and possibilities of different forms of biomass (live or dead, modified or immobilized) are also considered.

“…The C–N stretching vibration, C–H stretching vibration, and C–H stretching vibration corresponded to the peaks at 1043 cm –1 (A region), 1388 cm –1 (B region), and 2928 cm –1 (D region) in Figure i, respectively. The peak at 1633 cm –1 (C region) and 3440 cm –1 (E region) comes from the N–H crooking vibration and stretching vibration, indicating that EDA was bound to the CdS x Te 1– x nanobelts. − The XPS spectra of CdS x Te 1– x -EDA nanobelts are exhibited in SI Figure S5–S9. SI Figure S5 shows the XPS spectra of Cd 3 d region over CdS x Te 1– x -EDA nanobelts.…”

The photocatalysts for hexavalent uranium (U(VI)) reduction suffered from the low uranium uptake capacity and weak long-wavelength light absorption. Herein, we synthesized the CdS x Te 1−x nanobelts capped by ethylenediamine (EDA), which provided amino groups as the adsorption sites. With the increase of the Te content, the amino groups on the CdS x Te 1−x nanobelts decreased because of the variation of the electron density of Cd 2+ , whereas the light adsorption was enhanced due to the narrowed bandgap. In photocatalytic reduction of U(VI), the CdS 0.95 Te 0.05 -EDA nanobelts exhibited a considerable U(VI) removal ratio of 97.4% with a remarkable equilibrium U(VI) extraction amount on per weight unit of the adsorbent (q e ) of 836 mg/g. The bandgap structure and Fourier transform infrared spectroscopy (FT-IR) spectra analysis revealed that the optimum photocatalytic activity of CdS x Te 1−x nanobelts was achieved at a 5% of Te 2− doping, which balanced the factors of amino groups and bandgap. This adsorption-photoreduction process offers an ultrahigh uranium extraction capacity over wide uranium concentrations.
