Enhanced adsorption of carbon nanocomposites exhausted with 2,4-dichlorophenoxyacetic acid after regeneration by thermal oxidation and microwave irradiation†
Abstract
Graphene nanoplatelet–single-walled carbon nanotube hybrid papers exhausted with 2,4-dichlorophenoxyacetic acid were recovered by a combination of thermal oxidation and microwave irradiation. The recycling efficiency investigated after multiple saturation/regeneration cycles based upon changes in optical absorption spectra significantly exceeded the adsorption capacity of the original nanocomposites.
