Effects of monorhamnolipid and dirhamnolipid on sorption and desorption of triclosan in sediment-water system

► The solubilization enhancement of trilosan (TCS) by rhamnolipids was investigated. ► The sorption of rhamnolipids by the sediments was adequately described by Langmuir-type isotherm. ► The sorption and desorption of TCS mainly depend on the sediment composition and rhamnolipid structure. ► Dirhamnolipid was more effective than monorhamnolipid for TCS desorption from sediments.
