Commercially available microcrystalline cellulose (MCC) was functionalized using chlorosulfonic acid, while iron oxide nanoparticles (IONPs) were adsorbed on the surface of the cellulose derivative by the Massart’s co-precipitation method. The obtained magnetite-decorated sulfate cellulose nanoparticles (MDSCNs) were characterized via Fourier transform infrared (FTIR) spectroscopy, scanning-electron microscopy (SEM), and elemental analysis, while the acidity of the functionalized cellulose was determined using an acid–base titration with phenolphthalein as an indicator. Furthermore, in order to determine the adsorptive power of the obtained composite, a series of analyses were performed on aqueous amine pollutants using flame ionization detection gas chromatography (GC-FID). The results of this study clearly show how a bio-compatible green polymer as cellulose can be easy functionalized in order to improve its chemical and physical properties, obtaining a magnetic composite useful in water purification. Adsorption percentages up to 90% and a very small amount of composite used (100 mg) proved how our material can be a powerful tool in environmental remediation.

“…Lewatit can adsorb more Li than K and Na in oxalate containing lithium with pH 4 and 50 mL/hour flow rate [12]. In addition, resin with sulfuric acid groups had good adsorption for Li in pH range 4-10, which covers the pH of brine [13]. Notwithstanding, quantitative correlations for competing for another ion crucial in industrial design were not revealed.…”

Sorption of a series of alkali metals (Ca, Mg, Li, and K) from Bledug Kuwu’s Brine into Lewatit MonoPlus S-108 resins has been studied. Bledug Kuwu’s Brine comprised 15.11 ppm Li, 179.91 ppm K, 72.01 ppm Ca, and 29.76 ppm Mg. The adsorption was carried out by varying pH of brine (4, 6, 8, and 10) and contact time (1, 2, and 4 hours) with continuous flow in column test at room temperature. The result showed the quantity adsorbate in outer resin: K>Li>Ca>Mg in all conditions, which is 0.038–0.043 mmol/g lithium, 0.087–0.09 mmol/g potassium, 0.031–0.035 mmol/g calcium, and 0.023–0.024 mmol/g magnesium into outer resin surface. The selectivity factor to lithium followed Mg/Li > K/Li> Ca/Li in all conditions. Contact time variable provided high lithium separation after the adsorption process for 2–3 hours, while pH had little effect. FTIR results affirm that resin was changed at new peaks M-O-M at low wavenumber with polystyrene crosslinked-divinylbenzene matrix and contains the sulfonic type. The results obtained from ICP were fitted to isotherm models in ion exchange, as follows: Langmuir, Freundlich, Temkin, and Dubinin-Radushkevic models. The best model of lithium adsorption into Lewatit S-108 is represented by Freundlich and Temkin Model (R2 ≥ 0.82) with 1.0056 mg/g of adsorption capacity (Kf) and 64.885 J/mol of heat process of sorption.

“…Cellulose, as the most abundant renewable bioresource, has attracted significant attention for advanced materials and manufacturing in this epochal transition. Cellulose is one of the most abundant biomass resources in nature, and its hydrolysis and transformation to produce valuable chemicals are the focus of current research (Chen et al 2020). A comprehensive explanation of sustainable functional materials and classical spinning techniques as key applications has been provided (Petroudy et al 2021).…”

Salix holocellulose liquefaction products (SHLP) were prepared by liquefaction of the wood. A spinning solution of polyurethane (PU) and SHLP was prepared, and microspheres were obtained by electrospinning. The bonding of SHLP and PU-SHLP was characterized via FTIR. The conductivity and viscosity of spinning solution were characterized by conductivity meter and viscosity meter, respectively. The electrospun fiber morphologies were characterized by SEM. The results showed that PU was introduced into SHLP. The concentration of solution was the main factor that affected the morphology of microspheres, and the diameters of microspheres was from 0.18 to 1.18 μm. In addition, in this electrospinning system, the concentration of liquefied products in the mixed spinning solution was the major factor that affected the morphology of microfibers, and the diameters of microfibers were from 0.29 to 1.78 μm.
