According to increase of using quantity, people interested in the environmental influence by synthetic detergent. The main visible form when synthetic detergent dissolved in water is generating foams. This foam makes coating over water surface and prevents oxygen penetrating in water and make water more polluted with that result. To analyze, components and origins of the foam, and to make clear its environmental influence in this study. The analyzing objects are introducing water of sewage treatment plant from the a tributary to the Han River. After analysis, reached the conclusion like below, Analyzing foams and introducing water by sublation method, average return rate of standard LAS (1.0ppm) is 90%. LAS contents of foams analyzed by UV photometric method and HPLC method are 35.0ppm and 44.5ppm each, and AOS contents of foams analyzed by the same method are 0.6ppm and 0.4ppm each. We can find out by this study's analyzing results that the main components of foams are anion surfactant, it's content and in case of capric acid linoleic acid, it's contents.
