Generally, CNFs contain trace substances such as hemicellulose, which have a lower thermal degradation temperature than cellulose. Therefore, hemicellulose may decrease the thermal degradation temperature of CNFs. To increase the thermal stability of CNFs by removing hemicellulose, commercial CNFs were subjected to several cellulases and hemicellulases, and evaluated by thermogravimetric analysis. Our results showed that xylanase treatment for 1 h increased the pyrolysis temperature of the CNFs. Next, the basic sheet properties of enzyme-treated CNFs were investigated. The tensile strength of the CNF sheets decreased after enzymatic treatment, however, their contact angles increased.

In this study, we assessed the contribution of polymers forming the supramolecular structure of the cell wall (cellulose, hemicelluloses, and lignin) to compare grindability of plant biomass when using standard equipment with two types of mechanical action, the impact-shear mode in a planetary ball mill and the shear mode in an attritor. Individually, these types of grinding equipment are well upscaled to the industrial level, while their hypothetical combination with different ratios between individual “impact/shear” actions describes the micromechanics for most other grinding setups. Assessment of energy consumption and grinding productivity demonstrates that grinding in the impact–shear mode is more efficient compared to the shear one. Chemical removal of any polymeric component of the plant cell wall increases energy efficiency of grinding in the impact–shear mode up to ninefold. In the case of shear-type loads, each polymeric component of the cell wall contributes to grindability of the plant biomass. Partial hydrolysis of hemicelluloses has the strongest positive effect on subsequent grinding.

Then, PLA composite filaments containing 3–9 wt% CHG fillers were prepared through melt blending and extrusion process.

Nevertheless, certain dyes, such as malachite green (MG), could be extremely difficult to eliminate adequately using untreated cellulose, hence raising concerns regarding the successful applications of cellulose. This problem may be solved with zinc-treated cellulose, which improves adsorption efficacy by increasing surface area, porosity, and chemical reactivity. This study investigates the efficacy of ZnO-treated cellulose obtained from biomass pre-treatment, specifically focusing on enhancing the removal efficacy of MG. High-yield cellulose fiber was extracted from rice straw using a green solvent, which was further treated with ZnO and characterized to understand its structural and chemical properties. To study MG removal, equilibrium and kinetic studies were used to evaluate adsorption performance, and further advanced AI/ML-driven optimization improved the process efficiency. ZnO-treated cellulose dose of 0.4 g/L, MG concentration of 30 mg/L, pH 7, temperature at 30 °C, and stirring at 100 rpm yielded 98% MG removal efficiency. Using advanced computational approaches, the artificial neural network model (R<sup>2</sup> = 0.966) outperformed the response surface methodology model (R<sup>2</sup> = 0.91), demonstrating the potential for improved adsorption efficiency with ZnO-treated cellulose.

Decolorization is a vital step in the recycling and reuse of colored waste textiles.

This study aims to develop an efficient and eco-friendly Fenton-assisted decolorization method to remove reactive dyes, specifically reactive blue 21, from waste cotton fabrics to facilitate recycling and reuse. The decolorization process involved a two-step approach: pre-treatment with thiourea dioxide and ferrous ions (Fe<sup>2+</sup>), followed by oxidative decolorization using hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>). Parameters such as agent dosage, initial solution pH, temperature, and duration were optimized to achieve high decolorization efficiency while maintaining fabric strength. The optimized process achieved a decolorization rate of over 90%, with minimal tensile strength loss within 10%. Characterization techniques including Fourier Transform Infrared Spectroscopy, X-ray Diffraction, Thermogravimetric Analysis and Scanning Electron Microscopy revealed the structural and chemical transformations in the cotton fibers, providing insights into the decolorization mechanisms. The method also demonstrated high applicability across a range of reactive dyes, particularly azo-based dyes.

In this research, a combination of electrospinning and annealing treatment was employed to fabricate low-cost and stable silica gel incorporated chitosan composite nanofibers, which were served as an efficient adsorbent for adsorbing Pd<sup>2+</sup> ions from aqueous solution. The fiber morphology was analyzed by scanning electron microscopy (SEM). Brunauer–Emmett–Teller (BET) analysis and positron annihilation lifetime spectroscopy (PALS) were employed to analyze the microstructure. The surface area of composite nanofibers reaches the maximum of 81.46 m<sup>2</sup>/g with 23.1% loading of silica gel. These fiber adsorbents were used to adsorb the Pd<sup>2+</sup> ions in aqueous solution and the related factors of silica gel content, the annealing temperature and the adsorption parameters (e.g. adsorption time, solution pH, and initial Pd<sup>2+</sup> concentration) were investigated and optimized. The adsorption results demonstrate that the unique fibrous structure and the incorporation of silica gel significantly enhance the adsorption efficiency for Pd<sup>2+</sup> ions with a maximum adsorption capacity of ~ 113 mg/g. The adsorption mechanism analysis reveals the involvement of chelation and electrostatic interaction between the amino groups in chitosan and Pd<sup>2+</sup> ions. Thermodynamic analysis indicates that the adsorption process is endothermic and spontaneous with ΔH<sup>0</sup> and ΔS<sup>0</sup> values of − 26.59 kJ/mol and 96.02 J/mol K, respectively. Moreover, the fibrous adsorbent exhibits outstanding recyclability, retaining 85.2% of its initial adsorption capacity after five successive reuse cycles. In conclusion, this low-cost and high-performance fibrous adsorbent holds great potential for the efficient separation and recovery of precious Pd<sup>2+</sup> ions from industrial wastewater.</p></div>","PeriodicalId":511,"journal":{"name":"Cellulose","volume":"32 12","pages":"7223 - 7238"},"PeriodicalIF":4.8,"publicationDate":"2025-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144869017","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
