Soil acidification is a problem widely occurring worldwide, which severely threaten food security and agricultural sustainability. Calcium lignosulfonate (CaLS), a cheap and ecofriendly compound, is used for the first time to amend acid soil by utilizing its unique organic and inorganic functional moieties simultaneously. Both column leaching and incubation experiments were conducted to investigate the comparative effects of CaLS (four rates at 5, 10, 15, 20 g kg −1 ) and compared with conventional amendments, including gypsum (5 g kg −1 ), lignin (5 g kg −1 ), L + G (each at 5 g kg −1 ), and control. The soil pH, exchangeable acidity and base cations, organic carbon, and different Al fractions were determined to unravel the ameliorative performance and mechanism of the treatments. Regardless of application modes and dosages, the results demonstrated that CaLS incorporation significantly increased soil pH, exchangeable Ca 2+ , cation exchange capacity, and organic carbon and decreased the contents of exchangeable acidity, especially exchangeable Al 3+ . The ameliorative mechanism was that amendment material led to the displacement of H + and Al 3+ off soil colloids by Ca 2+ . These released H + and Al 3+ which complexed with lignosulfonate anions into soluble organo-Al were all quickly leached from the soil column. The CaLS addition enhanced the transformation of exchangeable Al 3+ and low-to-medium organo-Al complexes into highly stable organically bound fractions and immobilized into the soil. The complexing of CaLS functional groups with Al 3+ impeded Al 3+ from undergoing hydrolysis to produce more H + . As an environmental-friendly material, CaLS can be a promising amendment for soil acidity and Al toxicity amelioration.

Lignosulfonate (LS), as the most abundant technical lignin, is hard to depolymerize due to highly condensed structure. To overcome the limitation, in this work, NiMoO 4 /Al 2 O 3 catalyst with regulated acidity/hydrogenation activity was developed for highly efficient LS depolymerization . Results show that the performance of NiMoO 4 /Al 2 O 3 was improved by sulfur migration. Meanwhile Ni Mo alloy contributed to the good stability during LS depolymerization . The NiMoO 4 /Al 2 O 3 was favor for the intermediate compounds production by the cleavage of C O and C C bonds, which intermediate compounds were eventually hydrogenated to monomers by highly active MoS 2 . Also, NiMoO 4 /Al 2 O 3 and sulfonic groups play a synergistic role in the sulfur migration (only 39.1% bio-oil yield obtained by MoS 2 /Al 2 O 3 ). After reacting at 300 °C for 4 h, 81.7% of bio-oil yield with 95% desulfurization rate were obtained. Thus, it was demonstrated that an inexpensive catalyst was developed which can efficiently catalyze the depolymerization of lignosulfonate.

Depolymerized lignin products are very complex mixtures. Based on a depolymerization solution of commercially available sodium lignosulfonate under mild conditions, a fast and efficient method for the separation and direct characterization of the degree and efficiency of the acid-catalyzed depolymerization of lignin was developed in this study. Using an ultraviolet detector, the depolymerized lignosulfonate products were well separated and characterized according to the relative molar mass distribution on an advanced polymer chromatographic system with three ethylene-bridged hybrid columns having small pore sizes (45 Å) in series and tetrahydrofuran as the mobile phase. The developed advanced polymer chromatography method enabled the detection of low-molecular-weight lignin degradation products ( M n = 260–1100 Da) with high peak resolutions in less than 7.2 min. Furthermore, preliminary advanced polymer chromatography studies to determine the influence of reaction temperature on the depolymerized products indicated that the depolymerized aromatics fell in several molecular weight ranges with an extremely low dispersity. This new approach can be used for the rapid analysis of lignin depolymerization products.

The widespread use of petroleum-based plastic mulch films in agriculture has led to severe environmental pollution, which has driven increasing interest in the development of biodegradable plastics derived from biomass resources. Herein, eco-friendly composites/films were fabricated using soy protein isolate (SPI) and sodium lignosulfonate (LS) as the primary biomass components through a simple casting method. The SPI/LS composites exhibited impressive mechanical properties, including high tensile strength (15.4 MPa), fracture strain (290 %), toughness (33 MJ‧m −3 ), Young's modulus (100 MPa), and excellent fatigue resistance (maintaining 5 MPa strength after 10 cycles of repeated stretching at 150 % strain). These properties were closely linked to multiple molecular interactions within the composites. Fourier transform infrared spectroscopy and X-ray diffraction analysis revealed that the protein's secondary structure transitioned to a more ordered state, with enhanced hydrogen bonding between SPI and LS. Furthermore, the SPI/LS films demonstrated excellent UV-shielding, moisture retention capabilities, and enhanced crop seed germination rates. Plant seedling tests indicated that after biodegradation in soil, the films released nitrogen-containing ions such as NH 4 + vital for healthy root growth. Therefore, the eco-friendly and biodegradable SPI/LS composites/films hold great potential as mulching films for agricultural crop cultivation, improving crop yields while reducing the need for fertilizers.

Effective, safe, and rapid treatment of dye-contaminated wastewater is a challenging task at the global scale. In this study, lignosulfonate-based polycatecholamine and polyethersulfone composite (PES-PCA-LS) membrane was prepared by depositing aminated sodium lignosulfonate (LS) and catechol on polyethersulfone (PES) membrane. This membrane was characterized by various techniques and its performance was investigated using Congo red (CR) as the probe molecule. The results showed that the retention rate of CR solution by PES-PCA-LS membrane was above 99.5%. At this removal rate, one square meter of membrane could treat 351 L of CR waste solution (CR, 100 ppm; salt, 5,000 ppm). However, the retention rates of NaCl, Na 2 SO 4 , and K 2 SO 4 were found to be only 2.8%, 3.5%, and 0.9%, respectively. Besides, this membrane could target selective removal of CR from the mixed solution (CR/Rhodamine B). This PES-PCA-LS membrane also showed excellent cycling performance, with the removal rate maintained at about 97% at the tenth cycle. Thus, this study provides new ideas for the application of industrial lignin in the field of membrane separation for dye/salt or dye/dye mixed solutions.

Polyaniline doped with lignosulfonate (PANI/LGS) was prepared by using a facile oxidative polymerization of aniline with (NH4)2S2O8 as an oxidant, and the structure and morphology of PANI/LGS were investigated. As an active material for supercapacitors, the capacity retention rate of PANI/LGS was 75.1% with a growth of current density from 0.2 to 10 A g−1, indicating a high rate performance, and that of PANI was only 38.3%. For PANI/LGS, a specific capacitance of 377.2 F g−1 remained at 10 A g−1, and that of PANI was 183.7 F g−1. Moreover, the cycling stability was also measured in a two-electrode symmetrical capacitor at a current density of 1.0 A g−1. The capacity retention rate of PANI/LGS was 74.3% after 10 000 cycles, and that of PANI was 52.8%.

In the present study, a new solid adsorbent, lignosulfonate-graphene oxide-acrylamide (LS-GO-AM) ternary composite hydrogel possessing good mechanical strength and high dye adsorption capacity, was prepared by a simple polymerization, and used for the removal of dyes from aqueous solution. The adsorption property of a model dye, methylene blue (MB), onto the hydrogel was studied. The effects of adsorption time, initial pH, and concentration were investigated. When the initial MB concentration was 3 mg·L –1 at an LS-GO-AM concentration of 4 g·L –1 , the absorption was 98.36% while the solution was nearly decolorized. Moreover, adsorption kinetic and equilibrium data were described well with pseudo-second-order and Langmuir isotherm models for MB adsorption. The LS-GO-AM composite hydrogel with enhanced mechanical strength could be easily separated from the reaction system.

The nonisothermal crystallinization kinetic was performed on Polyvinyl alcohol (PVA) mixed with eucalyptus lignosulfonate calcuim (HLS) as the biobased thermal stabilizer, which was systematically analyzed based on Jeziorny model, Ozawa equation and the Mo method. The results indicated that the entire crystallization process took place through two main stages involving the primary and secondary crystallization processes. The Mo method described nonisothermal crystallization behavior well. Based on the results of the half time for completing crystallization, k c value in Jeziorny model, F(T) value in Mo method and crystallization activation energy, it was concluded that low loading of HLS accelerated PVA crystallization process, however, the growth rate of PVA crystallization was impeded at high content of HLS.

The solar-driven interfacial evaporation has attracted great attention for the purpose of alleviating freshwater shortage. Lignosulfonate (LS), a main byproduct of sulfite pulping processes, is an abundant natural resource but has not been reasonably utilized. To mitigate the above problems, biochar-based interfacial evaporators derived from LS for solar steam generation were studied in this paper. First, LS was used as a raw material for fabricating carbon materials by carbonization to construct LS-derived carbon (CLS). Meanwhile, LS-derived porous carbon (PCLS) in the presence of CaCO 3 as the activator was also prepared. Next, the two biochar powders, as solar absorbers, were crosslinked with polyvinyl alcohol to prepare the interfacial evaporation materials (PVA@PCLS and PVA@CLS). The open porous structure facilitated the capillary effect and water transport to the evaporator surface. It was also found that the light absorption of the materials could reach more than 97% in the 250–2500 nm range. Moreover, the water evaporation rate and the solar-to-vapor conversion efficiency of PVA@PCLS and PVA@CLS were 2.33, 1.82 kg m −2 h −1 , and 83.7%, 69.3% respectively under 1 sun (1 kW m −2 ) irradiation. The solar-to-vapor conversion efficiency of PVA@PCLS was much increased after the carbonization of LS. In addition, the material cost of PVA@PCLS is only $38.3/kg due to the low price of LS. Therefore, this work provides an economic and efficient strategy for solar-driven desalination and a possible way for the high-value utilization of lignin. Highlights Biochar was produced through the carbonization of lignosulfonate. PCLS has smaller particle size and larger multistage pore. Green, efficient interfacial evaporation materials derived from biochar were prepared by simple processes. Among the three interfacial evaporation materials, PVA@PCLS has the largest water evaporation rate and solar-to-vapor conversion efficiency. The material cost of PVA@PCLS is rather low.

Effect of the molecular structure of lignosulfonate-based polyoxyethylene ether (LS-PEG) on the enzymatic hydrolysis of Avicel and corn stover was investigated. With the increase of PEG contents and M w of LS-PEG, glucose yield of corn stover increased from 16.7% to 51.9%. When LS-PEG was compounded with cationic surfactant cetyltrimethylammonium bromide (CTAB), the enhancement of glucose yield of corn stover was further increased from 45.3% to 62.8%. Sulfonic group of LS-PEG preferentially interacted with quaternary ammonium group of CTAB by the electrostatic attraction to form a similar non-ionic surfactant CTAB-LS-PEG. CTAB-LS-PEG showed electrically neutral and more hydrophobic, and blocked more nonproductive adsorption of cellulase on the lignin. Therefore, CTAB-LS-PEG enhanced enzymatic hydrolysis efficiency of lignocelluloses more significantly. The understanding developed in this study can help to develop potential approaches and strategies for effective application of lignosulfonate to improve bioconversion of lignocellulosic biomass.

Lignosulfonate (LS) can enhance lignocellulose saccharification by forming complexes with cellulase. However, the composition and spatial structure of lignosulfonate–cellulase complexes (LCCs) are not clear. This study employed quartz crystal microbalance with dissipation monitoring, surface plasmon resonance, and small-angle X-ray scattering (SAXS) to investigate the composition and spatial arrangement of LCCs. Results revealed that LS molecules self-assemble into aggregates in buffer (pH 4.8), which subsequently form distinct complexes with cellulase depending on the molar ratio. At LS:cellulase ratios of 4:1 or higher, one LS aggregate binds to a single cellulase molecule, while at lower ratios, one LS aggregate binds to multiple cellulase molecules. SAXS analysis revealed that cellulase’s adsorption domain interacts with LS aggregates, suggesting a mechanism to reduce nonproductive binding to lignin. Ionic strength was found to influence the complex formation through electrostatic interactions. These findings elucidate the structural basis for LS-mediated saccharification, providing insights for optimizing lignocellulosic biomass conversion.

Sodium lignosulfonate (Na-LS) was used to modified montmorillonite to form lignosulfonate-montmorillonite (LS-MMT). The as-prepared samples were characterized by various equipment to analyze the surface morphology and structure of the pure and reformed samples. The adsorption capability ( q e , mg/g) of LS-MMT or Ca/Na-MMT for Pb(II) and Cu(II) at different reaction intervals, the concentration of metal ions, temperature, and pH were studied by batch adsorption experiments. The results revealed that LS-MMT displayed a higher adsorption capacity than Ca/Na-MMT. The pH of solutions had a great influence on the q e of the two adsorbents, and the q e was slightly enhanced with temperature increasing. The isotherm and kinetic experiments studies indicated that the adsorption of heavy metal on LS-MMT or Ca/Na-MMT fit well with the Langmuir model and pseudo-second-order kinetic model. The competitive adsorption showed that LS-MMT had a stronger affinity for Pb(II) than Cu(II), which was different from Ca/Na-MMT. Additionally, the desorption experiment showed that LS-MMT had a stronger ability to lock heavy metal ions than Ca/Na-MMT in an acidic environment with pH ranging from 3 to 5.
