摘要
含苯氧基的非离子型和阴离子型表面活性剂在一定激发波长下可发出特定波长的荧光，在稀溶液中荧光发射强度与其浓度成正比，不受溶液里存在的其他物质的影响，在适当条件下相互之间也无影响。本文报道了用荧光检测复合驱油体系中的ＯＰ１０、石油磺酸盐和ＯＰ１０＋石油磺酸盐的结果。此法选择性高，灵敏度高，操作简便，可望用于复合驱油体系中表面活性剂的分析、研究。
The determination of surfactant(s) in the alkaline/surfactant/polymer flooding solutions was an uneasy job.For this purpose,the method of fluorescence emission by phenoxycontaining surfactants in dilute solutions is suggested.The fluorescence emission intensity changes linearly with in the extent of low surfactant concentrations below the critical micelle concentration (CMC)and is not influenced by the presence of alkali,polymer PHPAM and salts.Under certain conditions the fluorescence emission by petroleum sulfonate and OP10 in a multicomponents aqueous solution can be detected independently.This method is highselective,sensitive (the lowest detectable concentration 10-7mol/L)and microanalytical(the amount of test solution 2～3μL).
