SNF (Sodium Naphthalene Formaldehyde) is a commonly used concrete admixture in the construction industry. SNF is a water-soluble polymer that is produced by the sulfonation of naphthalene followed by condensation with formaldehyde. It is a highly effective dispersant that is used to improve the workability, …

sodium Lignosuofonate used in aquaculture Sodium lignosulfonate is a natural polymer derived from lignin, which is a complex organic compound found in the cell walls of many plants. It is commonly used as a dispersant, binder, and surfactant in various industrial applications, including in aquaculture. …

Lignin is the largest reservoir of aromatic compounds on earth and has great potential to be used in many industrial applications. Alternative methods to produce lignosulfonates from spent sulfite pulping liquors and kraft lignin from black liquor of kraft pulping process are critically reviewed herein. …

Dispersants and concrete additives (plasticizers) account for the widest use of lignosulfonates and sulfonated lignin. This is due to their appropriate molecular weight (10 000–50 000 g mol@1) and anionic charge density (0.1–0.9 meq g@1), stemming from the presence of functional groups.[2, 13, 45, 78, …

Lignin and Lignosulfonate has a high potential available biopolymer that can be converted into various bioproducts. *e main utilization of lignin is for low-grade fuel by burning that can cause wastage of resources and environmental pollution . Only a limited quantity of lignin has been …
