建立一种快速简便地将驱油用阴离子表面活性剂从原油中分离出来的方法 .即在极性硅胶柱上用不同极性的溶剂淋洗分离 ,将阴离子表面活性剂富集在淋洗液中 .用指示剂法及红外光谱法对分离情况进行检测 .对表面活性剂的定量测定表明 ,回收率可达 99%± 2 %
A rapid and easy method of separating oil-displacing anionic surfactants from crude oils was established by rinsing and separating with polar solvents on a polar silica gel column, concentrating anionic surfactants in the eluent In the indicator method and infrared spectroscopy to detect the separation of the quantitative determination of surfactants showed that the recovery rate of up to 99% ± 2%
