The Effect of Microemulsion Composition on the Adsorption of Petroleum Sulfonates on Berea Sand/Montmorillonite Clay Adsorbents
The adsorption from microemulsion of two petroleum sulfonates, PDM-334 and TRS 10-410, on Berea sand/montmorillonite clay adsorbents has been studied to determine: 1) the effect of microemulsion composition, specifically its relative oil and brine content, on sulfonate adsorption; 2) the effect of adsorption on the microemulsion composition and interfacial tension behavior. Whereas the degree of sulfonate adsorption can be determined by conventional methods (e.g. UV spectroscopy), one must utilize a microemulsion property which is a sensitive function of the relative oil and brine content of the microemulsion in order to determine the adsorption-induced changes in the microemulsion composition. This can be accomplished by the use of the microemulsion specific refraction.
