Carbon from Lignin and Sodium Lignosulfonate
Carbon from Lignin and Sodium Lignosulfonate ，need to make clear the Applications for lignin and lignosulfonates are limited today due to the undefined structure and varying properties of the substance. However, lignin, as the second most abundant bio-resource besides cellulose and the bio-resource with one of the highest natural carbon contents, has the potential to…

Lignosulfonate(Lignosulphonate)
Lignosulfonate(Lignosulphonate) are obtained from sulfite pulping processes wherein cellulose is extracted from wood in the pulp industry. The so-called sulfite pulping process involves mixing sulfur dioxide (SO2) with an aqueous solution of base to generate the raw liquor for cooking the wood. In water, the sulfur dioxide forms sulfurous acid (H2SO3), which degrades and eventually sulfonates the lignin by…

Lignosulfonate(lignosulphonate)
Lignosulfonate(lignosulphonate) (often abbreviated as LS) were one of the first dispersants added as an admixture to concrete. Lignosulfonates have been used since the 1930s as plasticizers or water reducers. Mixed with concrete, their use has afforded the beneficial effects of retarding the setting time and reducing the amount of mixing water required. The only lignin…

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…
