Description
Sodium lignosulfonate (lignosulfonic acid, sodium salt) is used in the food industry as a de-foaming agent for paper production and in adhesives for items that come in contact with food. It has preservative properties and is used as an ingredient in animal feeds. It is also used for construction, ceramics, mineral powder, chemical industry, textile industry (leather), metallurgical industry, petroleum industry, fire-retardant materials, rubber vulcanization, organic polymerization

Case Study

Synthesis of High-Efficiency Adsorbent Based on Sodium Lignosulfonate/Polyethylenimine/Sodium Alginate

Huang, Yimin, et al. Journal of Hazardous Materials, 2022, 436, 129270.

A new adsorbent with excellent adsorption capacity can be easily synthesized through simple cross-linking of sodium lignosulfonate/polyethylenimine/sodium alginate (SL/PEI/SA). The SL/PEI/SA can be further used to remove toxic heavy metal ions Cr(VI) from wastewater.
Synthesis of SL/PEI/SA adsorbent
· 0.2 g of SA, 0.2 g of PEI, and 0.2 g of SL are added to a 50 mL beaker containing 15 mL of water and was stirred at 25 ℃.
· After 12 h, 0.7 mL of glutaraldehyde was added to the above beaker and stirred continuously for 5 h at 25 ℃.
· Subsequently, the solution was dropped into a 3 % of CaCl2 solution to form beads. After allowing this solution to stand for 12 h, the beads were filtered and washed three times with water, and subsequently suspended in an aqueous solution with a pH of 1 for 24 h.
· Finally, the beads were repeatedly washed with water and freeze-dried to obtain SL/PEI/SA beads.
