Adsorptive removal of methylene blue by rhamnolipid-functionalized graphene oxide from wastewater
摘要:
A rhamnolipid-functionalized graphene oxide hybrid has been prepared by one-step ultrasonication for the first time.The adsorption isotherm follows BET model and Freundlich model simultaneously.The pseudo-second-order model fits adsorption kinetic well.The maximum methylene blue uptake capacity is 529.10mg/g at 298K.The application to real dye wastewater and the renewability are highly feasible.
