【Abstract】 A new, simple and rapid method was established to separate anoinic surfactant, which is used in increasing of oil recovery, from oil. The crude oil containing the anoinic surfactant was eluted with a series of organic solvents, in turn, in the order of the increased polarity on a polar silica column to separate the surfactant from other oil components completely. The separation effect was tested by methylene blue acidic indicator and IR spectroscopy. It was proofed to be an effective and practical method.更多还原
