Abstract
A method for preparing a crude oil solution for analysis, including adding water to a porous adsorbent to obtain a supported water substrate, having a plurality of water monolayers disposed on the porous adsorbent. The method further includes exposing the crude oil solution to the supported water substrate for a period of time; separating the supported water substrate from the crude oil solution; washing the supported water substrate with a water immiscible solvent to remove at least one hydrocarbon; displacing water from the plurality of water monolayers and the at least one interfacially active compound from the porous adsorbent with an alcohol and a co-solvent to obtain a displaced phase. The displaced phase can include the water, the at least one interfacially active compound, the alcohol, and the co-solvent. Finally, the method can include drying the displaced phase to isolate the at least one interfacially active compound.
