The high lignin content had the potential to make Sodium Ligno Sulfonate (SLS) Surfactants by reacting Lignin with Sodium Bisulfite. Isolation of Lignin From Black Liquor was carried out at room temperature of 30°C, using sulfuric acid (H 2 SO 4) and 1N NaOH. The purpose of this study was to characterize SLS formed both physically and chemically.

Sulphonation of lignin has been considered as a promising step to produce lignosulfonate which may serve as dispersant, flocculant, and surfactant. The aim of present study was to compare the synthesis of sodium lignosulfonate (SLS) from different lignin feedstocks namely commercial lignin and lignin isolated from black liquor (BL) of pulp and paper …
time, sodium hydroxymethyl sulfonate/lignin mole ratio, and sodium concentration were investigated. Furthermore, previ-ous reports highlighted that the more sulfonated groups of lignosulfonates and greater the negative charge density, the greater the resulting corrosion eciency of the SLS [32, 33].
