“…Recently, various techniques have been applied for recovery and removal of uranium from its leach liquors or effluents such as precipitation (Mellah, Chegrouche, & Barkat, 2007;Zhang, Dodge, Malhotra, & Francis, 2013), co-precipitation (Aydin & Soylak, 2007;Reeder et al, 2001), solvent extraction (Agrawl, Shrivatav, & Mnom, 2000;Quinn, Wilkins, & Soldenhoff, 2013;Zhu, Pranolo, & Cheng, 2016), chromatographic extraction (Dietz, Philip, Sajdak, & Chiarizia, 2001;Prasada, Metilde, & Gladis, 2006), ion exchange (Gu, Ku, & Brown, 2005;Pulhani, Dafauti, & Hegde, 2012;Solgy, Taghizadeh, & Ghoddocynejad, 2015), membrane dialysis (Kedari, Pandit, & Gandhi, 2013;Bockris, 1972), solid phase extraction (Barbette et al, 2004;Keshtkar, Irani, & Moosavian, 2013;Song et al, 2012;Yousif, El-Afandy, Abdel-Wahab, Mubark, & Ibrahim, 2015;Zou & Zhao, 2012), ultrafiltration (Drozdzaka et al, 2016), nanofiltration (Shena & Sch€ aferb, 2014), resin-in-pulp (Sreenivas & Rajan, 2013), biosorption (Saini & Melo, 2015) and electrodeposition (Ko, Lim, Choi, Chung, & Kang, 2015). Most of these methods suffer from technical, economical and health problems related to selectivity, long time of extraction and large quantity of hazardous materials used but the ion exchange resins appear to be one of the most effective techniques owning to its cost-effective, versatile and simple features to operate for removing trace levels of ions (Bhatnagar, Kumar, & Sillanp, 2011;Rafatullah, Sulaiman, Hashim, & Ahmad, 2010).…”

The kinetic, equilibrium and thermodynamic characteristics of U(VI) recovery by the strong base anion exchange resin Ambersep 920U SO 4 from Gabal Gattar sulfate leach liquor have been determined. Batch sorption experiments are performed to evaluate the optimum conditions at pH2, 200 mg resin dose for 120 min contact time at room temperature. The maximum sorption capacity reaches to 58 mg/g at 298 K. The kinetics data are well described by the pseudo-second-order kinetic model at different uranium concentrations. The experimental results obtained at various temperatures showed that the adsorption pattern on the studied resin has followed Langmuir isotherm model. The evaluation of thermodynamic parameters (free energy change DG, enthalpy change DS, entropy change DH, activation energy E a and sticking probability S*) indicate that the adsorption process is spontaneous in nature, endothermic, randomness and chemisorptions. Uranium(VI) can be completely desorbed from the loaded resin using 0.5 M HNO 3 solution. Finally, the optimized factors have been carried out for uranium(VI) recovery from G. Gattar leach liquor.

“…When adsorption process follows pseudo first order, it implies that the metal ions are physically adsorbed onto the sorbent. On the other hand, the pseudo second order indicates that the adsorption process is a chemical progression [87,88]. The pseudo first, second order kinetic, Elovich and intraparticle diffusion models for Cr(VI) and Pb(II) are illustrated in Fig.…”

Hydrogel composites comprised of N,O carboxymethyl chitosan crosslinked with different weight ratios of acrylic acid and fabricated with nanoclay particle were prepared via gamma irradiation at 25 kGy irradiation dose. The prepared composites were coded as CsAA1Cl, CsAA2Cl and CsAA3Cl based on the weight ratio of acrylic acid to the chitosan derivative. The claimed hydrogels were characterized by FTIR, TGA and XRD. The TGA data implied that the incorporation of clay nanoparticles enhanced the thermal stability of the composites; the decomposition temperature increased up to 500 °C for CsAA3Cl. Three AFM outcomes were used to compare the surface features of the samples; topography, height and surface roughness. The topography data reveals that the nanoclay particles incorporated in CsAA3Cl are intercalated and exfoliated. Then, the optimized sorbent (CsAA3Cl) was investigated as green sorbents for chromium (VI) and lead (II). The data revealed that CsAA3Cl displayed maximum removal performance towards both lead and chromium with removal efficiencies 125 mg/g and 205 mg/g respectively at the optimum application conditions within 90 min only. Also, it was found that the optimum pH value was 9 for chromium and 8 for lead. The data proved that the adsorption of both cations followed pseudo-first order kinetic model. The prepared composites showed acceptable metal uptake capacity at three successive cycles. Graphical Abstract

“…Also added to the cellulose-GMA mixture was a combination of one mL isopropyl alcohol and 25 mL cyclohexane. All of the ingredients were combined in a flask containing 145 mL (%) polyvinyl alcohol dissolved in isopropanol and heated for 3 h in a water bath at 70-80 °C with constant stirring [30]. Grafted cellulose (GC) is a thick white precipitate that was generated, filtered out, rinsed with ethanol and distilled water, and then dried in the air.…”

A considerable increase in the importance of vanadium globally and its common uses in many manufacturable alloys made it a target for much scientific research interested in extraction and recovery. A solid modified cellulose sorbent (GCIHQ) was prepared by simple grafting of cellulose, then immobilized with hydroxyquinoline, and examined as a sorbent for V(V) ions. FT-IR, TGA, BET, and SEM–EDX investigations were used to characterize the GCIHQ. A higher surface area for the synthesized GCIHQ resin has been recorded (65.8 m2/g) more than the used cellulose (21.7m2/g). Several vanadium sorption parameters using the modified GCIHQ from the sulfate medium were optimized namely contact time, pH, initial vanadium ions concentration, sorbent dose, and sorption temperature. The kinetics results revealed that the sorption of vanadium ions upon the synthesized sorbent followed the pseudo-second-order with R2 of > 0.99, which indicated that the sorption mechanism was chemical interaction. The sorption process was studied using Freundlich, Langmuir, Dubinin–Radushkevich, and Temkin isotherm models to describe the adsorbent-adsorbate interaction. The Langmuir model was the most fitting model with the experimental results; the experimental adsorption uptake of 113 mg/g was matched with that of the calculated results. The activation energy (Ea) for adsorption was 12.91 kJ.mol−1, indicating the process is to be chemisorption. Thermodynamic characteristics with ΔH of 13.46 kJ/mol and a ΔS 115.15 J/mol.K revealed the endothermic and spontaneous nature.
