“…More importantly, their adsorption mechanism were clarified, that is, the electrostatic force, hydrogen bonding, and π-π stacking interactions were the main driving force on MG adsorption onto LPPNs. Wang et al [106] produce three lignin esters (LEs) with different hydrophilic properties by directly esterification reaction using methacrylate anhydride, itaconic anhydride, or maleic anhydride. Subsequently, these LEs were copolymerized with acrylic acid, and obtained three types of hydrogels with the highest adsorption capacity for methylene blue (2445 mg/g).…”

As a major component of lignocellulosic biomass, lignin has lots of fascinating properties, such as regeneration, biocompatibility, antioxidant, hydrophilicity, unique aromatic structure, and various functional groups, which make them become interesting natural polymer raw material, and attracted more and more attention. In particular, the rich functional groups of lignin can be easily functionalized through various synthesis methods, which can endow lignin‐based polymers with new structure and function. These functional lignin‐based polymers are widely used in environmental remediation, smart hydrogel materials, catalysis, biomedical, etc. However, its various sources and types, the complex structure, relatively weak chemical reactivity, the unstable processing property, and few high value‐added products limited their practical applications. With the development of lignin varieties, modified reagent, synthesis methods, and polymerization process, many works had been published for the synthesis and application of lignin‐based polymers. In this review, the lignin isolation, modification strategies, polymerization method and process, and the promising applications were summarized and analyzed in recent years. Specially, the recent advances in the preparation of high excellent adsorbents from deconstructed lignin products are highlighted from the synthesis methods and adsorption mechanism perspective. Finally, we discussed these challenges in the green and controllable synthesis of lignin‐based polymers, and prospected their functional applications.

“…Unfortunately, most of the textile industries do not follow the effluent discharge regulations properly and release huge amount of untreated or partially treated dye containing effluents directly into the environment [6]. Dye effluents released through smelting, printing, mining, petroleum refining, and car manufacturing industries have already become a worldwide environmental problem [7]. The industrial effluents are rich in persistent pollutants such as heavy metals, sulfur, nitrate, naphthol, soap, formaldehyde, coloring and chlorinated compounds [8,9].…”

The developmental activities, industrialization and urbanization are responsible for contamination of soil and aquatic system. Textile industry is one of the important and largest industrial sector of India which is responsible for economic growth of nation. Textile industry effluent contain heavy metals, dye, inorganic and organic contaminants and show negative impact on environment and human health. In the present study, survey was conducted in the Pilkhuwa industrial area of Hapur district, western Uttar Pradesh and responses of local residents were collected through questionnaire after interview and group discussion. The local residents reported that water of the Pilkhuwa industrial area is not clean and safe for drinking and most of the people of the area are suffering from various health related disorders such as skin diseases, asthma, and typhoid etc. Hence, there is an urgent need of cost-effective, eco-friendly and sustainable technologies for decontamination of industrial effluent before its release into the environment.

Lignocellulosic nanofibrils (LCNFs) isolation is recognized as an efficient strategy for maximizing biomass utilization. Nevertheless, achieving a 100% yield presents a formidable challenge. Here, an esterification strategy mediated by the equilibrium moisture in biomass is proposed for LCNFs preparation without the use of catalysts, resulting in a yield exceeding 100%. Different from anhydrous chemical thermomechanical pulp (CTMP0%), the presence of moisture (moisture content of 7 wt%, denoted as CTMP7%) introduces a notably distinct process for the pretreatment of CTMP, comprising the initial disintegration and the post‐esterification steps. The maleic acid, generated through maleic anhydride (MA) hydrolysis, degrades the recalcitrant lignin‐carbohydrate complex (LCC) structures, resulting in esterified CTMP7% (E‐CTMP7%). The highly grafted esters compensate for the mass loss resulting from the partial removal of hydrolyzed lignin and hemicellulose, ensuring a high yield. Following microfluidization, favorable LCNF7% with a high yield (114.4 ± 3.0%) and a high charge content (1.74 ± 0.09 mmol g−1) can be easily produced, surpassing most previous records for LCNFs. Additionally, LCNF7% presented highly processability for filaments, films, and 3D honeycomb structures preparation. These findings provide valuable insights and guidance for achieving a high yield in the isolation of LCNFs from biomass through the mediation of equilibrium moisture.
