OSTI ID:6380679
Our work during the past year has focussed on the adsorption of promising anionic and ethoxylated surfactants on reservoir minerals and on the effect of surfactant structure on adsorption. Calorimetry was used to investigate the interactions of the anionic/nonionic mixtures in bulk and at solid/liquid interface. The calorimetric work emphasized on the mixed surfactant system of anionic sulfonate and ethoxylated alcohol and has resulted in identifying the thermodynamic parameters that determine the nature of mixing of these surfactants in bulk and on alumina surface. Work has been initiated on the interactions of SDS/triton X-100 mixtures on complex minerals such as kaolinite. We also examined the role of structure of surfactant with particular emphasis on the position of the sulfonate group on the benzene ring. The hydrophobicity of the surfactant was affected significantly by altering the position of the sulfonate on the ring and consequently affected the adsorption behavior. Each segment of this project is summarized below. 9 refs., 16 figs., 6 tabs.
