Chemical agent detection in the oilfield produced liquid plays a key role in the dynamic evaluation during ASP (alkali/surfactant/polymer) flooding. A new method was proposed for analysis of trace carboxylate surfactant with the UV spectrophotometer determination. This method is simple, accurate and rapid with a wide linear range. The method recovery is in the range of 94.4%–103.1%, and the relative standard deviation is only 1.38%. In considering the actual situation of oil production, the impact of alkali, polymer, crude oil and other interfering factors on the determination was explored, and the results were very satisfying.
