Abstract:

Surfactants have been widely used in detergents, emulsifiers and other daily chemicals, however, surfactants could cause risks to the ecological environment and human health when discharged with domestic sewage into the water environment if the surfactant concentration were too high. Therefore, it is important to monitor and quantify the surfactants in water environment. Due to the diversity in types and structures of surfactants present in the water environment, as well as the presence of matrix interference, pretreatment such as purification and enrichment is needed and should be combined with accurate instrumental analysis, thus to achieve effective identification and quantification. Herein, the commonly used pretreatment technology for water samples containing surfactants has been reviewed, including liquid-liquid extraction, solid phase extraction, solid phase micro extraction, magnetic solid-phase extraction and ultrasonic-assisted extraction, as well as the analysis methods including two-phase titration, electrochemical analysis, chromatography, spectroscopy, etc. By sorting out the applicable condition, range, and advantages and disadvantages of each method, it is suggested that the selection of pretreatment and detection method depends on the characteristics and concentration of surfactants. It is pointed out that, the technology of on-line extraction and enrichment, the automation and the portable on-site rapid real-time detection are the focuses of future research on surfactant detection. This paper could provide a reference basis for the monitoring and assessment of surfactants in water environment.
