“…First, it can reduce metal ions with suitable redox potential (eg. Ag + ) into zero‐valent state and secondly, it is a nanoparticle stabilizer preventing the formation of aggregates ,. The more detailed studies on gold and silver nanoparticles stabilized by LS (AgNPs‐LS, AuNPs‐LS) revealed also that the phenolic groups and negatively charged sulfonic groups on the LS chains are favorable for the efficient adsorption of heavy metal ions such as Ni 2+ , Co 2+ , Pb 2+ , Cd 2+ .…”

Lignosulfonate‐stabilized gold nanoparticles (AuNPs‐LS) were synthesized and subsequently used as a complexing agent for mercury ions. The obtained AuNPs‐LS/Hg2+ complex was characterized by means of various physicochemical techniques such as UV‐vis spectroscopy, transmission electron microscopy and cyclic voltammetry. Furthermore, the resulting complex was evaluated as an electrode modifier for the development of amperometric sensors. Upon sufficient negative potential, the bound mercury ions are reduced to form an amalgam with AuNPs‐LS. Thus, the performance of glassy carbon electrode (GCE) modified by AuNPs‐LS/Hg film was investigated as an electrochemical sensor in the determination of Tl+ ions in a 0.05 M EDTA at pH 4.5. The presence of the mercury containing film improves the analyte accumulation due to its ability to form a fused amalgam with thallium. The presented data indicate that the GCE/AuNPs‐LS/Hg modified electrode shows better performance toward Tl+ determination in comparison to bare GCE. The stripping anodic peak current of thallium was linear over its concentration range from 1.7⋅10−7 to 5.0⋅10−6 M. The detection limit (3σ) was estimated to be 1.4⋅10−7 M. The proposed method was successfully applied for the determination of thallium ions in real samples of soil derived from the area of the copper smelter near Głogów (Poland).

“…LS was usually incorporated with other materials as a stabilizing agent of a counter polyion for the formation of nanoparticles. LS‐Ag and LS‐Au nanoparticles were synthesized by mixing LS solution with the solutions of silver‐ammonia complex ((Ag[NH 3 ] 2 ) + ) and KAuCl 4 , respectively . The obtained nanoparticles were mono‐dispersed.…”

“…LS-Ag and LS-Au nanoparticles were synthesized by mixing LS solution with the solutions of silverammonia complex ((Ag[NH 3 ] 2 ) + ) and KAuCl 4 , respectively. [47,48] The obtained nanoparticles were mono-dispersed. By replacing commonly used toxic stabilizing agents (eg, amines, thiols, pyridine derivatives, and phosphines) with biocompatible LS from renewable sources, the production of LS-Ag and LS-Au nanoparticles may be possible.…”

In pulp production processes, lignin is generated in large quantities as a by‐product. It is often burned to generate heat and electricity. Despite the large‐scale production of lignin, its utilization in high‐value applications has remained a challenge. Recently, the production of lignin nanoparticles (LNP) and lignin polymers has gathered attention. The potential to use LNPs as reinforcement filler, UV absorbent, antioxidant, and drug carrier has been reported, while lignin polymers might be suitable for the production of composites, hydrogels, flocculants, and coagulants. This review paper provides insights into the production and application of LNP and lignin polymers. In addition, the challenges associated with the characterization and use of these products are comprehensively reviewed.
