Unraveling the surface activity and micellization characteristics of linear alkyl benzene sulfonate in aqueous solution

Abstract

Abstract The aggregation behavior of various neutralizing agents (monovalent and diamine bases) has been investigated for linear alkylbenzene sulfonate. Measurements employing conductivity at temperature (298.15 K, 303.15 K, 308.15 K, and 313.15 K) and surface tension at 298.15 K have been determined to study micellization and surface active properties. The conductivity versus concentration plot elucidated CMC and dissociation of counterion (α). Additionally, surface active parameters ϒCMC, A min, π CMC, and τ max were investigated via tensiometry using the Wilhelmy plate procedure. The wettability characteristic of the surfactant solution was determined using contact angle analysis. Furthermore, the particle size parameters were determined using DLS measurements. The Gemini salts of LABS portrayed improved efficiency and demonstrated economical in domestic and industrial applications.
