“…A single, strong band at 1029 cm −1 is the result of the stretching of C-O, characteristic of the primary alcohols. Moreover, the absorption band visible for 652 cm −1 is typical for the lignosulfonates and is the result of the vibrations of the S-O bond [38,39]. The spectrum obtained for the lignosulfonic acid (ligH) does not exhibit significant differences from the ligS spectrum.…”

Lignin is an abundantly occurring aromatic biopolymer that receives increasing attention as, e.g., a biofiller in polymer composites. Though its structure depends on the plant source, it is a valuable component showing biodegradability, antioxidant, and ultra-violet (UV) absorption properties. Lignosulfonates, a by-product of the paper and pulping industries formed as a result of the implementation of the sulfite process, have been used in the presented study as a raw material to obtain a sulfonamide derivative of lignin. Hereby, a two-step modification procedure is described. The obtained materials were investigated by means of FTIR, WAXD, SS-NMR, SEM, and TGA; the results of spectroscopic investigations confirm the formation of a sulfonamide derivative of lignin via the proposed modification method. The obtained modified lignin materials showed significantly improved thermal stability in comparison with the raw material. The internal structure of the lignosulfonate was not altered during the modification process, with only slight changes of the morphology, as confirmed by the WAXD and SEM analyses. The manufactured sulfonamide lignin derivatives show great promise in the potential application as an antibacterial filler in advanced biopolymeric composites.

“…However, most of the industrial lignins are directly burned or wantonly discharged (Zhao et al 2020b). After appropriate modification, industrial lignin can be used as adsorbent (Zhou et al 2020), dispersant (Zhou et al 2015), water reducing agent (Zhou et al 2016a), and rubber reinforcing agent (Gregorová et al 2006). Unfortunately, although the utilization of lignin is widely concerned, the comprehensive utilization ratio of lignin is less than 5% (Li et al 2015).…”

Cr(VI), a serious threat to human health, widely exists in the effluents of various industrial processes.. In this paper, the potential of industrial lignin for efficient removal of Cr(VI) from wastewater were systematacially investigated, including pulping black liquor lignin (BLN), enzymolysis lignin (ELN), and SPORL pretreatment spent liquor (FS). The structure characterizations of three lignins were investigated by TG, FTIR, BET, SEM, and XPS. Among these three lignins, BLN showed the highest adsorption amount of Cr(VI) and best selectivity in wastewater simulation. According to the Langmuir model, the calculated maximum adsorption amount of Cr(VI) on ELN, BLN, and FS was 765.60, 880.57, and 721.58 mg g -1 , respectively. The adsorption of Cr(VI) by industrial lignins was a chemisorption process, during which Cr(VI) was reduced to low toxic Cr(III). This paper provided a promising application for the effective utilization of industrial lignins.

“…As shown in Figure b, two new peaks at 723.2 and 710.1 eV appear in the iron-adsorbed biocomposite adsorbents, which correspond to Fe 2p 3 . The deconvoluted peaks of O 1s in Figure c consist of CO at 532.6 eV and COOH at 531.4 eV . After iron adsorption, the peak of 532.7 eV shifts to the left.…”

The essential nutrients (e.g., iron) for food production are nonrenewable resources, which cannot satisfy the need of a fast-growing global population. Meanwhile, excessive irons accumulated in iron-rich water pose an adverse effect on human and ecosystem health. Thus, it is necessary to develop a cost-effective and eco-friendly adsorbent for reclaiming irons from iron-accumulated water and which cannot satisfy the need of a fast-growing global population. Meanwhile, excessive irons accumulated in iron-rich water pose an adverse effect on human and ecosystem health. Thus, it is necessary to develop a cost-effective and eco-friendly adsorbent for reclaiming irons from iron-accumulated water and these irons for growing crops. In this study, a simple gelation–solidification process aided by phase separation is developed to fabricate a biodegradable alginate/polyvinyl alcohol/lignosulfonate (SA/PVA/LS) three-dimensional (3D) biocomposite adsorbent. Calcium chloride and boric acid are used as cross-linkers between polymers with hydroxyl groups. This bioadsorbent owns a multiporous architecture, ample functional groups, and enhanced total pore volume. A multilayer adsorption mechanism endows it with a high iron adsorption capacity (52 mg/g) via Langmuir simulation and a physiochemical adsorption mechanism. The porous 3D structure of the biocomposite could be observed from SEM and CT scanning. After iron loading, it can be applied as an excellent substitute for a commercial EDTA-Fe micronutrient to promote plant growth with a comparable ratio of root to shoot length. This eco-friendly, highly efficient, and filled 3D bioadsorbent is expected to open a door to achieving circular recovery of plant essential plant nutrients from waste resources for crop production.
