“…Raw lignin could be also directly incorporated into a polymeric matrix to serve as a pollutant adsorbent as well. A chitin/lignin hybrid material was synthesized as an effective adsorbent for the removal of hazardous metals such as Ni 2+ , Cu 2+ , Zn 2+ and Pb 2+ from model solutions as well as real industrial wastewaters [ 93 ]. Nair et al also reported a novel chitosan-lignin composite for effective adsorption of metal ions from wastewater [ 94 ].…”

The quest for converting lignin into high-value products has been continuously pursued in the past few decades. In its native form, lignin is a group of heterogeneous polymers comprised of phenylpropanoids. The major commercial lignin streams, including Kraft lignin, lignosulfonates, soda lignin and organosolv lignin, are produced from industrial processes including the paper and pulping industry and emerging lignocellulosic biorefineries. Although lignin has been viewed as a low-cost and renewable feedstock to replace petroleum-based materials, its utilization in polymeric materials has been suppressed due to the low reactivity and inherent physicochemical properties of lignin. Hence, various lignin modification strategies have been developed to overcome these problems. Herein, we review recent progress made in the utilization of functionalized lignins in commodity polymers including thermoset resins, blends/composites, grafted functionalized copolymers and carbon fiber precursors. In the synthesis of thermoset resins such as polyurethane, phenol-formaldehyde and epoxy, they are covalently incorporated into the polymer matrix, and the discussion is focused on chemical modifications improving the reactivity of technical lignins. In blends/composites, functionalization of technical lignins is based upon tuning the intermolecular forces between polymer components. In addition, grafted functional polymers have expanded the utilization of lignin-based copolymers to biomedical materials and value-added additives. Different modification approaches have also been applied to facilitate the application of lignin as carbon fiber precursors, heavy metal adsorbents and nanoparticles. These emerging fields will create new opportunities in cost-effectively integrating the lignin valorization into lignocellulosic biorefineries.

“…Lignin as one of the lignocellulosic materials can be used as an effective and resistant sorbent for the removal of many different potential pollutants from wastewaters. It is characterized by mechanical resistance, hydrophilic character, easy functionalization and the possibility to be used in different regimes and forms (Peterson 2012;Ciesielczyk et al 2017;Bartczak et al 2017;Atifi et al 2017;Klapiszewski et al 2014a, b;Cuia et al 2015;Xu et al 2015;Severtson and Banerjee 1996;Xiny et al 1994;Mamleeva and Lunin 2016;Abdolaki et al 2014;Demirbas 2004;Gue et al 2008;Dizhbit et al 1999;Da Silva et al 2011;Albadarin et al 2011).…”

This study presents the sorption capabilities of biopolymeric microspheres with commercial kraft lignin. The suspensionemulsion polymerization method was employed to obtain microspheres in spherical forms. Before copolymerization lignin was modified with methacryloyl chloride to increase its affinity for monomers. Two different types of microspheres (hybrid and non-hybrid) with the increasing quantity of lignin were studied. In the hybrid ones, divinylbenzene (DVB) and methacrylated kraft lignin (L) were used as organic compounds whereas triethoxyvinylsilane (TEVS) was applied as an inorganic one. The second type of microspheres was synthesized without the addition of TEVS. There were also applied two materials without a lignin component for comparison purposes. The hybrid lignin-containing microspheres exhibited a more developed porous structure than the non-hybrid ones. Their specific surface areas were in the range of 454-522 m 2 /g and 2305 m 2 /g, respectively. The results of swelling studies of synthesized materials in typical organic solvents and distilled water were presented. Additionally, in acetone and water, tendency to swell depending on time has been determined. The prepared microspheres were tested as sorbents for removal of fluorine containing phenolic compounds from the aqueous solutions using the solid phase extraction (SPE) technique. A mixture of: phenol (Ph), 2-fluorophenol (2-FPh), 2,6-difluorophenol (2,6-DFPh) and 2,4,6-trifluorphenol (2,4,6-TFPh) as testing compounds was applied. The prepared porous polymers possessed good sorption properties towards the testing compounds.

“…In developing countries, removal of heavy metals from wastewater is normally achieved using advanced technologies such as advanced oxidation processes, biological methods, ultrafiltration, extraction, ion exchange, electrochemical methods, and adsorption. 1,5) However, these technologies do not seem to be economically feasible because of their relatively high cost, and developing countries may not be able to afford such technologies. 1) Therefore, there is a growing requirement for cost-effective, efficient, and novel technologies for the treatment of wastewaters including heavy metals before their discharge into receiving water bodies.…”
