Lignosulfonates used in agriculture
Potassium Lignosulfonate and Ammonium lignosulfonate can be used in agriculture Soils treated with ammonium lignosulfonate generally had lower pH than untreated control soil (Fig. 1A). The pH reduction was greater with 0.5 and 1.0%, than with the 2.0% ALS mixture. All ALS treatments caused an increase in total soil bacterial population (Fig. 1B). In general,…

Lignosulfonate used for dust suppression
A more environmentally friendly solution is organic sulfonates like lignosulfonate. They are byproducts of the lumber industry and control dust in the same manner as hygroscopic salts. The major difference is that the material, which looks like molasses is organic, non-toxic, and won’t control equipment. In order to find the best dust control agent, the…

Conductance of Aqueous Solutions of Lignosulfonate and Poly(styrene sulfonate)
A procedure for isolating the high molecular-weight fraction of a commercial lignosulfonate sample by size exclusion chromatography is described together with the desalting process for that fraction. Conductance of aqueous solutions of the lithium, sodium, and potassium salts of the original lignosulfonate, the isolated lignosulfonate, and a standard poly(styrene sulfonate) sample were then measured at…

Effective adsorption of heavy metal ions by sodium lignosulfonate reformed montmorillonite
Sodium lignosulfonate (Na-LS) was used to modified montmorillonite to form lignosulfonate-montmorillonite (LS-MMT). The as-prepared samples were characterized by various equipment to analyze the surface morphology and structure of the pure and reformed samples. The adsorption capability (qe, mg/g) of LS-MMT or Ca/Na-MMT for Pb(II) and Cu(II) at different reaction intervals, the concentration of metal ions,…

Lignin
Also called wood lignin,An aromatic polymer compound found in plant fibers. It has the function of strengthening cell wall and binding fibers in plant tissues. Its composition and properties are relatively complicated, and it has extremely strong activity. It cannot be digested by animals and can be transformed into humus in the soil. If lignin…

Calcium lignosulfonate Properties
About Calcium lignosulfonate Properties,need to make clear what is calcium lignosulfonate firstly.Calcium lignosulfonate (referred wood calcium) is a multi-component polymer anionic surfactant, the appearance of brown powdery substance, slight aroma, molecular weight is generally 800 to 10000, with a strong dispersion, bonding, chelation. Currently calcium lignosulfonate products have been widely used as a cement water…

Lignin
Lignin is a poylmer present in the structure of many polar groups, more particularly hydroxyl groups, lignin with strong intermolecular and intermolecular hydrogen bond energy, and therefore the original lignin insoluble in any solvent . Separation of lignin, because of reduced synthesis and degradation occurs, many physical properties change, the change in solubility resistance. Alkali…

WHAT IS LIGNOSULFONATE
Lignosulphonate, or lignosulfonate, or sulfonated lignin, (CAS No. 8061-51-6) are water-soluble anionic polyelectrolyte polymers: they are byproducts from the production of wood pulp using sulfite pulping. Most delignification in sulfite pulping involves acidic cleavage of ether bonds, which connect many of the constituents of lignin. Lignosulfonates are obtained from sulfite pulping processes wherein cellulose is extracted from wood…
