The purpose of this study was to investigate the removal efficiency of surfactants by Oenanthe javanica that is one of aquatic plants in Korea. The surfactants used in this research include linear alkylbenzene sulfonates(LAS), α-sulfo fatty acid methyl esters(MES), and alkylbenzene sulfonates(ABS). The result showed that LAS and MES were more effectively removed by Oenanthe javanica probably because these have a chain of linear carbon than on ABS with a branched carbon structure.
