Abstract
Using the capillary penetration wetting technique, the influence of surfactant structure on wettability modification of hydrophobic granular surfaces was examined. Linear and branched hydrocarbon chain sulfates, 5 mol monodisperse ethoxylates and 5 mol monodisperse ethoxysulfates were used as surfactants and resin-coated sand as the hydrophobic granular surface. Both the surfactant type and hydrocarbon chain branching were observed to exert a significant influence on the rate and effectiveness of wetting. Wetting rates for ethoxylates > sulfates > ethoxysulfates. Wetting effectiveness for sulfates > ethoxylates. For a given surfactant type, hydrocarbon chain branching was observed to increase wetting rate and effectiveness.
