Abstract
Abstract
The waste of pulp and paper industry in the form of Black Liquor still contained a large amount of lignin (12-46%). 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 (H2SO4) and 1N NaOH. The purpose of this study was to characterize SLS formed both physically and chemically. Characteristics of SLS were formed compared to commercial SLS. The SLS purification results were carried out by comparing the SLS results of the experiments with commercial SLS using Fourier Transform Infra Red (FTIR) equipment, and the purity was tested by UV-Vis. For Enhanced Oil Recovery (EOR), SLS was tested based on its characteristics using screening tests.
