Because of its wide range of material sources, high specific surface area, and advantageous electrochemical characteristics, cellulose biochar derived from natural lignocellulosic raw materials has been extensively applied as electrodes for energy storage materials. To produce carbon materials with improved qualities, lignocellulosic substrates often need to be pretreated, activated, and modified. In this study, corncob was processed with bisulfite to break down its recalcitrant structure, followed by direct use of the pretreated substrate to avoid the post-pretreatment washing step and take full advantage of the generated lignosulfonate (LS) in the next pyrolysis process. The residual LS in the pretreated sample not only increased the specific surface area of the corncob-biochar, but also introduced the heteroatom S. The biochar obtained through pyrolysis at 900 °C with KOH activation from unwashed pretreated corncob (ABU-900) had a specific surface area of 3130 m 2 /g, and it displayed a high coulombic efficiency of 94.1% after 5000 cycles in a three-electrode system. Owing to the successful introduction of heteroatoms, an asymmetric supercapacitor device (ABU-900//activated carbon) delivered an excellent specific capacitance of 141.2 F/g at a current density of 1 A/g and an energy density of 43.7 Wh/kg with a power density of 619 W/kg. This work offers a new and simple route for preparing cellulose biochar-based electrodes from lignocellulose waste.

Lignin is the largest natural reservoir of aromatic compounds while its intricate polymeric structure complicates the reuse of lignin-derived waste. Herein, we report the development of lignin-based NH 3 adsorbents by upcycling sodium lignosulfonate (SLS) from spent paper pulp liquor. The demethylation of SLS was carried out to obtain the demethylated SLS (DSLS) and subsequently the pelletized DSLS@binder adsorbents were prepared using DSLS and three binders. The results indicate that the optimized 95% DSLS@PVA pellets with binder dosage of 5 wt% PVA (polyvinyl alcohol, PVA) exhibit the NH 3 adsorption capacity of 11.5 mmol g −1 , along with remarkable selectivity uptake for NH 3 /N 2 (3573) and NH 3 /CO 2 (1380). Moreover, the 95% DSLS@PVA pellets demonstrate ultra-fast adsorption kinetics (half-capacity uptake time of merely 38 s). Column breakthrough tests showed that the 95% DSLS@PVA pellets achieved NH 3 retention time of 370 min g −1 in a ternary gas mixture of NH 3 /N 2 /CO 2 (1 %/98 %/1%), with a dynamic adsorption capacity of 2.07 mmol g −1 . In addition, the 95% DSLS@PVA has a good balance between mechanical strength and NH 3 uptake cycle performance. This work provides a sustainable strategy for valorizing lignin waste into high-performance NH 3 adsorbents.

The thermal washing of oily sludge using sodium persulfate (SD) assisted by sodium lignosulfonate surfactant has been demonstrated to be an effective method for oily sludge remediation. To further explore the underlying mechanisms of this process, a systematic study was conducted by simulating oily sludge systems consisting of saturated hydrocarbons (SaH), aromatics hydrocarbons (ArH), resins (Res), and asphaltenes (Asp). The effects of reaction conditions, such as pH, sodium lignosulfonate alkyl (LSA) concentration, SD concentration, and washing temperature, were analyzed. Furthermore, the oxidative kinetic mechanism during the reaction process was investigated. The results demonstrated that neither petroleum hydrocarbons nor SD underwent significant chemical transformations when exposed to LSA, while SD exhibited a marked oxidative degradation effect on all four types of hydrocarbons. Oxidation kinetics indicated that sodium hydroxide played a catalytic role, with SD being the main oxidant and particularly efficient in degrading Asp and Res. Meanwhile, LSA contributed to the removal of hydrocarbons by reducing the surface tension of the solution, enhancing solubilization. This study not only elucidates the central role of SD in the thermal washing process but also provides a solid theoretical foundation for the practical application of this technology in oily sludge treatment.

Heteroatom-doped carbon photocatalysts have attracted increasing attention since they are inexpensive, environmentally friendly, and highly efficient. Herein, sulfur-doped carbon photocatalysts were prepared by a one-step low-temperature carbonization method using sodium lignosulfonate (SLS) as a starting material. The physicochemical properties of the carbon photocatalysts were characterized by N 2 adsorption-desorption, X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, and X-ray photoelectron spectroscopy (XPS), and so on. Compared with the carbon photocatalyst derived from alkali lignin, the sulfur-doped carbons from SLS can improve the degradation of tetracycline by nearly 40%. Sulfur species, i.e., sulfone and sulfoxide, can reduce the bandgap and promote the separation and transfer of photogenerated charge carriers under visible light irradiation. The recycling experimental results of S-C-N 2 -12 illustrate that the catalyst is stable without a remarkable loss in photocatalytic degradation of tetracycline after five successive runs, suggesting that the sulfur-containing species coordinated on the carbon surface are relatively stable. The results of radical-assisted electron spin resonance (ESR) and radical scavenger experiments show that h + plays a major role in the degrading of tetracycline. These findings suggest that the sulfur-doped carbon photocatalysts have a great potential in pollutant degradation and wastewater treatment.

Sodium oxalate (Na 2 C 2 O 4 ) is an excellent phosphorus-free agent, but in sodium oxalate-containing detergents with sodium dodecylbenzene sulfonate (SDBS) and sodium carboxymethyl cellulose (CMC), significant ash deposition occurs on cotton fabrics. SDBS is the main anionic surfactant in modern detergents and cotton fiber is the most commonly used textile fiber. In this study, sodium lignosulfonate (LS) was investigated for its ability to prevent redeposition in SDBS-Na 2 C 2 O 4 -CMC-LS formulations. The effects of LS on ash content, whiteness, optimum washing temperature, calcium oxalate morphology, zeta potential and surface tension were carefully analyzed. The results showed that the addition of LS significantly improved the prevention of ash deposits on cotton fibers. The ash content was less than 0.46% and a small amount of particles were scattered on the cotton fibers. LS showed good dispersibility but had little effect on the washing power and zeta-potential.

Dyes are indispensable for the rapid development of society, but untreated dye wastewater can threaten human health. In this study, an adsorbent (SA/SL/CCS/PEI@MNPs) was synthesized by one-pot method using magnetic nanoparticles (MNPs), sodium alginate (SA), sodium lignosulfonate (SL), carboxylated chitosan (CCS) and polyethyleneimine (PEI). The adsorbent was mesoporous micrometer-sized particles with pore size of 34.92 nm, which was favorable for dynamic column experiments. SA/SL/CCS/PEI@MNPs possessed pH-responsive performance. Under acidic condition, the maximum adsorption capacities for anionic dyes (tartrazine, reactive black-5, indigo carmine) reached >550 mg/g. Under alkaline condition, those for cationic dyes (methylene blue, methyl violet, neutral red) exceeded 1900 mg/g. The function of the various modifiers was investigated. The results indicated that the incorporation of SL, CCS and PEI was able to provide plenty of sulfonate, carboxylate and amino/imine reactive groups so that adsorption capacities of dyes were improved. The adsorption mechanism was explored by FTIR and XPS. At the same time, the adsorption mechanism was more deeply analyzed using molecular dynamics simulations and radial distribution function. It was demonstrated that the dyes adsorption on the SA/SL/CCS/PEI@MNPs was mainly due to electrostatic attraction and π-π interaction. In addition, the adsorbent had good reusability, and the removal still reached over 90 % after five cycles. In conclusion, the adsorbent displayed a broad prospect for the adsorption of organic dyes.

The treatment of oily sludge (OS) can not only effectively solve environmental pollution but also contribute to the efficient use of energy. In this study, the separation effect of OS was analyzed through sodium lignosulfonate (SL)-assisted sodium persulfate (S/D) treatment. The effects of SL concentration, pH, temperature, solid–liquid ratio, revolving speed, and time on SL adsorption solubilization were analyzed. The effects of sodium persulfate dosage, demulsification temperature, and demulsification time on sodium persulfate oxidative demulsification were analyzed. The oil removal efficiency was as high as 91.28%. The results showed that the sediment was uniformly and finely distributed in the S/D-treated OS. The contact angle of the sediment surface was 40°, and the initial apparent viscosity of the OS was 56 Pa·s. First, the saturated hydrocarbons and aromatic hydrocarbons on the sediment surface were adsorbed by the monolayer adsorption on SL. Stubborn, cohesive oil agglomerates were dissociated. Sulfate radical anion (SO4−·) with a high oxidation potential, was formed from sodium persulfate. The oxidation reaction occurred between SO4−· and polycyclic aromatic hydrocarbons. A good three-phase separation effect was attained. The oil recovery reached 89.65%. This provides theoretical support for the efficient clean separation of oily sludge.Keywords:oily sludge;sodium lignosulfonate;adsorption demulsification;separation;recovery

Moisture electricity generation (MEG) devices based on biomass materials often face limitations in practical applications due to their poor power generation performance. To address this challenge, this study developed a biomass-based MEG device by chitosan and sodium lignosulfonate, significantly improving the energy output of biomass-based moisture generation devices. The MEG device achieves an open-circuit voltage up to 1.4 V and a short-circuit current of approximately 40 μA·cm −2 at a relative humidity of 75 %, enabled by the synergy of multiple mechanisms. Additionally, the device exhibits excellent linear scalability and supports series-parallel configurations, enabling it to power small electronic devices such as calculators and light-emitting diodes, as well as serve as a sensor for respiration detection. This work presents an innovative strategy for utilizing biomaterials in energy generation, offering new opportunities for sustainable development and advancing green energy technologies.

In this study, two environmentally-friendly macroscopically formal (PVF) composited sponges (PL and PLS) functionalized with lignin and lignosulfonate, respectively, were fabricated by a one-step mechanical foaming method. PLS, obtained with the fed mass ratio of 0.3:1 lignosulfonate to PVF in the preparation process, possessed a large specific surface area of approximately 22.396 m 2 /g, a three-dimensional skeleton structure with a skeletal density of 3.236 g/cm 3 , and 0.338 mmol/g of acidic oxygen-containing groups. Thus, it showed a high adsorption capacity of 0.16–0.24 mmol/g in removing seven antibiotics, of the popular fluoroquinolones (FQs) family from water. The contributions of hydrogen bonding, electrostatic attraction (EA) and π-π electron donor-acceptor interaction to the adsorption of FQs onto the PL and PLS sponges were analyzed systematically by investigating the pH dependence of the adsorption capacity, and the changes in adsorption of two sub structural analogs of FQs as molecular probes, and by performing theoretical calculations. The EA between the acidic oxygen-containing groups on the sponges and the amino groups of FQs played a dominant role in adsorption in near neutral conditions, leading to a superior adsorption performance for PLS. Overall, the composited sponges have the advantages of simple production, environmental-friendliness, convenient recycle, and low cost, which renders them potentially viable in treating real wastewater containing FQs.

The preparation and application of biorenewable carbon-based catalyst are attracting increasingly attention in the field of green and sustainable chemistry. Here, a facile and low-cost lignosulfonate-based carbonaceous solid acid (LSS) was availably prepared via directly sulfonating lignosulfonate that was from sulfite pulping industry, and used to catalyze biomass-derived furfuryl alcohol to yield versatile butyl levulinate. The fabrication and properties of LSS were highly sensitive to the sulfonation conditions (i.e., lignosulfonate-to-H 2 SO 4 ratio and temperature). The physicochemical properties of the as-prepared LSS were well characterized using BET surface area, acid–base titration, SEM, XRD, FT-IR, XPS, and TGA techniques. The LSS contained –SO 3 H, –COOH and phenolic –OH groups and was ideal to perform the reaction of furfuryl alcohol with n-butanol to obtain butyl levulinate in yield higher than 95% at 110 °C for 8 h with catalyst dosage of 15 g/L. Meanwhile, the catalyst deactivated increasingly with a recycle number that was attributed to the adsorption of formed polymeric by-products on the active catalyst sites, and the slightly deactivated catalyst after plain sulfonation treatment was found to remain active with an almost unchanged product yield in consecutive cycles. This work highlights an economic, eco-friendly, sustainable and promising protocol for catalytic upgrading of bio-based compounds.

Emulsified asphalt is a critical component of low-temperature pavement materials and plays a pivotal role in determining the durability of asphalt mixtures. Lignosulfonate, with advantages such as facile preparation, environmental friendliness, recyclability, and energy conservation, has been used in various fields, but the insufficient emulsifying capacity limits its application as an emulsifier for asphalt. To meet the needs of emulsified asphalt as pavement materials, the modification of sodium lignosulfonate (SL) was conducted by graft copolymerization and the Mannich reaction, resulting in two kinds of emulsifiers with high performance for asphalt emulsion. The optimal conditions for both modification processes were thoroughly examined by using ductility as the key indicator. The molecular composition and structure of the products were characterized by using Fourier transform infrared spectroscopy. Additionally, the emulsification performance and surface activity of the modified SL were evaluated, and the particle size of the emulsified asphalt was determined. The emulsification performance and the surface activity of the modified SL were significantly improved compared with those of the original SL. Notably, the emulsified asphalt by the modified SL exhibited superior performance and enhanced storage stability. The ductility of the emulsified asphalts at 15°C increases from 46.3 to ~70 mm, as well as the storage stability from 4.8% to ~2% before and after the addition of the modified SL. In contrast, the emulsifier with rich amide and amine groups by graft copolymerization is superior to that by the Mannich reaction for asphalt emulsification.

Abstract Lignin is a typical biological macromolecule with a three-dimensional network structure and abundant functional groups. It has excellent ionic complexation ability and amphiphilic molecular structure characteristics. In this study, the carbon steel anticorrosion performance of sodium lignosulfonate (SLS) in an acid solution was evaluated using the weight loss method, electrochemical measurements, scanning vibration electrode technique (SVET), and surface characterization methods. SLS exhibited excellent corrosion inhibition efficiency for Q235 carbon steel in 1 mol·L -1 HCl, reaching a maximum value of 98%. A low SLS concentration of 20 mg·L -1 resulted in the maximum corrosion inhibition efficiency, which remained nearly constant at higher SLS concentrations. The SVET test demonstrated that the formation of an SLS adsorption film can impede corrosion. This study confirms the significance of the application of green biomass resources in the field of metal corrosion protection and green functional materials. Graphical abstract
