“…The typical outstanding absorption maxima peak confirmed the reduction of Ag + ions to Ag 0 and the formation of LS–Ag NPs at 418 nm ( Figure 1 a). Our findings agree with other Ag NPs synthesized using lignosulfonate molecules, where the synthesized Ag NPs exhibited typical SPR peaks at 410–420 nm [ 15 , 17 , 38 ].…”

“…The characteristic peak at 1448 cm −1 is assigned to the aromatic ring in the lignosulfonate. Moreover, the peaks at 1078 and 1178 cm −1 correspond to the sulfonic groups (-SO 3− and S=O) of LS, respectively [ 15 ]. Additionally, the absorption peaks in the range of 1000 and 800 cm −1 were related to aromatic vibrations groups of C=O, C-O, and C-H [ 3 ].…”

“…LS has been extensively used as a dispersing agent for pesticides, dyes, and oil, as flocculating agents for water purification, and as a concrete water-reducer due to its certain advantageous physicochemical properties, as well as its being abundantly available, inexpensive, and eco-friendly [ 12 , 13 ]. Moreover, LS has been studied for metal NPs and metal–organic NP synthesis, for example LS-mediated ZnO NPs as an antibacterial agent; LS-fabricated Ag NPs for the removal of dyes; NaLS/SiO 2 composite sphere particles for drug delivery; LS-synthesized Ag NPs for heavy-metal sensing, and also for electrocatalytic applications [ 14 , 15 , 16 , 17 , 18 , 19 ].…”

This study explored the potential of abundantly available sodium lignosulfonate (LS) as a reducer and fabricating agent in preparing silver nanoparticles (LS–Ag NPs). The operational conditions were optimized to make the synthesis process simpler, rapid, and eco-friendly. The prepared LS–Ag NPs were analyzed via UV–Vis spectroscopy, X-ray diffraction spectroscopy, Fourier transform infrared spectroscopy, and high-resolution transmission electron microscopy. Results demonstrated that LS–Ag NPs were of crystalline structure, capped with LS constituents, and spherical in shape with a size of approximately 20 nm. Under optimized conditions, LS–Ag NPs exhibited significant photocatalytic activity in Reactive Yellow 4G degradation. The effects of photocatalyst (LS–Ag NPs) dosage, dye concentration, and its reusability for dye degradation were studied to make the process practically applicable in textile wastewater treatment. Additionally, the synthesized LS–Ag NPs displayed significant free radical scavenging against 2-diphenyl-1-picrylhydrazyl (DPPH) with an IC50 value of (50.2 ± 0.70 µg/mL) and also exhibited antidiabetic activity in terms of inhibition in the activity of carbohydrate-degrading marker enzyme α-glucosidase with an IC50 value of (58.1 ± 0.65 µg/mL). LS–Ag NPs showed substantial antibacterial potential against pathogenic strains, namely E. coli and S. aureus. In conclusion, LS–Ag NPs can be a reliable and eco-friendly material for their possible application in the treatment of dye-containing wastewater and have a great perspective in the biomedical and pharmaceutical sectors.
