This work focuses on the precipitation of lignin from kraft black liquor (BL) along with its valorization into nanoparticles (LNP). Two organic acids namely, acetic acid, and lactic acid were used for as an alternative to sulfuric acid. An optimization study was carried out determine effect three key variables, namely type, temperature, pH, isolation yield purity lignin. The showed that all factors primarily influenced yield, while precipitated varied only around 1 % between minimum maximum purity. Further, method selected preparation LNP. aimed observe concentration, surfactant concentration over properties prepared nanoparticles. results a smaller nanoparticle size maximization phenolic content achieved 35 mg/mL, 10 (w/w lignin), pH 5. Additionally, antibacterial activity LNPs against Escherichia coli, Staphylococcus aureus, Pseudomonas aeruginosa bacteria evaluated. minor aureus. Overall, demonstrates potential through production LNP desirable properties.

Researchers utilized NaBH4 to gently modify alkali lignin, resulting in L-Sx-ty-Pz with high hydroxyl value and decolorization, significantly enhancing the strength of composite films cellulose nanofibers (CNF). Without strict pH control, content modified lignin reached as 9.14 mmol/g. The CF/L-S1-t120-Pu film achieved a maximum stress 45.33 MPa, representing 116% 77% increase compared pure CNF crude films, respectively. reduction effect imparted transparency film, broadening its applications. Additionally, film's excellent antibacterial flame-retardant properties provide strong support for industrial utilization.
