“…52,53 Owing to the exceptional structural and physical properties, availability, biocompatibility, and biodegradability of biopolymers, they represent a highly promising choice for the generation of sustainable materials with enhanced adsorption behavior. [54][55][56][57] Consequently, biopolymer-based adsorbents have exhibited fabulous adsorption behavior not only toward phosphates but also toward a wide variety of noxious contaminants, including pharmaceuticals, 51 hydrocarbons, 58 pesticides, 59 uoride, 60 nitrate, 61 heavy metals, 62,63 dyes 64 and nitro-aromatic compounds. 65 Amongst these brilliant biopolymers, anionic alginate (Alg) is a collective family produced from algae and bacteria at a comparatively low cost.…”

“…The Th(IV)-adsorption capacities of AlNN and CFBS@AlNN adsorbents remained unchanged because their adsorption sites were gradually occupied until they reached saturation. , The interaction behavior between AlNN and CFBS@AlNN adsorbents and Th(IV) ions was described by applying the Langmuir and Freundlich models. The linear relations of the Langmuir and Freundlich isotherm models can be represented by the following equations − C normale q normale = 1 K normalL Q normalo + ( 1 Q o ) C normale R normalL = 1 1 + K normalL C normalo ln nobreak0em.25em⁡ q normale = ln nobreak0em.25em⁡ K normalf + 1 n 0.25em ln nobreak0em.25em⁡ C normale …”

Long-term exposure to radioactive elements through water, such as thorium ions, has undesirable impacts and may cause serious health problems like cancer. Therefore, this manuscript originally targets detection and elimination of thorium ions from water samples, even at trace concentrations. Herein, a novel ligand, (Z)-N-carbamimidoyl-4-((3-phenylnaphtho[1,2-b]furan-5-yl)diazenyl)benzenesulfonamide (CFBS), was synthesized for fluorometric detection of thorium ions. Then, the prepared CFBS-ligand was well-immobilized and grafted with mesoporous γ-Al2O3-like nanoneedles to prepare a hybrid mesoporous γ-Al2O3-like nanoneedles (CFBS@AlNNs) adsorbent. The CFBS@AlNNs adsorbent was employed to adsorb and remove thorium ions from an aqueous solution. The results indicated that trace concentrations of thorium ions could be detected and removed with good sensitivity and selectivity. The findings confirmed superior adsorption efficiency (98%) and capacity (142 mg/g) of used CFBS@AINNs toward Th(IV) ions at pH 4. The mechanism of Th(IV)-adsorption was explained mathematically through kinetic studies, isotherm models, and computational studies. One of the key advantages of CFBS@AlNNs is its thorium selectivity even in the presence of other coexisting ions. The CFBS@AlNN design showed significant thorium-removal/adsorption capacity, although multiple reuse/recycling followed a simple desorption process. Given its high selectivity, fast diffusion, and highly efficient adsorption, the CFBS@AlNNs sorbent can be considered a potential adsorbent to remove and recover thorium ions from various water samples and can be used to prevent the health risks related to the long-term and direct exposition of thorium ions.

“…The linear isotherms equations are listed in Table S2. The R 2 values (Table 2) signalize that the CR adsorption onto α-kGl-AmCsSB obeys Langmuir and Freundlich models, suggesting that the adsorption process occurs via chemical and physical interactions (Gomaa et al 2022c). Furthermore, it was found that the computed q max under Langmuir is 434.78 mg/g at room temperature.…”

Sandwich-like construction of a new aminated chitosan Schiff base for efficient removal of Congo red

Herein, a novel sandwich-like α-ketoglutaric acid Schiff base-aminated chitosan composite (α-kGl-AmCsSB) was fabricated by reacting α-ketoglutaric acid and aminated chitosan. The as-fabricated α-kGl-AmCsSB was inspected by diversified characterization tools to determine its morphology, surface charge, and chemical composition as well as define the linkage pathway between α-kGl and AmCs. The SEM images demonstrated a spongy network of AmCs with interconnected pores structure which turned to a quite rough surface due to the linkage of α-kGl to the free amine groups of AmCs. Notably, the XPS and FTIR spectra suggested the linkage of α-kGl to the amine group of AmCs. The experimental results implied the superior adsorption efficiency of Congo red (CR) onto α-kGl-AmCsSB since the maximum adsorption capacity (qmax) reached 434.78 mg/g at 25 °C and pH 3. Based on kinetics data, the adsorption of CR on α-kGl-AmCsSB followed pseudo-second-order model. Furthermore, D-R model infers that the CR adsorption onto α-kGl-AmCsSB occurred via physical interactions since the E value < 8 kJ/mol. The recyclability test was implemented for five cycles with R% > 72%. More importantly, the adsorption mechanism of CR onto α-kGl-AmCsSB was proposed and discussed. Ultimately, the novel sandwich-like α-kGl-AmCsSB exhibited advanced adsorption performance toward CR along with excellent reusability. Based on these results, we recommend more modifications on α-kGl-AmCsSB for exploiting its remarkable advantages and applying it on a large scale.
