%X The removal of chlorobenzene (CB) in wastewater by micellar-enhanced uhrafihration (MEUF)using three single surfactants,such as sodium dodecyl sulfate (SDS),cetyltrimethylammonium bromide(CT-MAB)and Tween-80(TW80),and the mixed surfactant SDS-TW80,was investigated.The results showed that the effect of standing time on CB removal was neglected while that of shaking time changed little after CB was shaken for 1 h.The removal efficiencies of CB increased with surfactant concentration increasing.The removal efficieneies of CB by single surfactants followed the order as TW80>CTMAB>SDS.which appeared to be negatively related to the critical micelle concentrations (CMC) and the hydrophile-lypophile balance values(HLB)of surfactants.It was also indicated that the removal efficiencies of CB by the mixed surfactants SDS-TW80 could be significantly increased compared with the single anionic surfactant SDS.The removal effects could be enhanced while the mass ratios of nonionic surfactant TW80 in the mixed surfactants increased.In addition,the greater the concentration of surfactant,the less the permeat flux.The permeat flux by single surfactants followed the order as SDS>TW80>CTMAB.The permeat flux could be reduced when the mass ratio of nonionic surfactant in the mixed surfactant increased.
