In this paper, the adsorption composite materials based on the incorporation of diatomite (DE) and graphene oxide (GO) were developed and characterized by different techniques (UV-vis, Raman, SEM and XRD). The adsorption behaviors for methylene blue (MB) as received GO-DE composite materials adsorbents have been investigated. The results indicate that GO-DE composite materials can significantly hoist the adsorption capacity of DE and improve the separation trouble of GO with outstanding adsorption ability. It is concluded that the GO-DE composite material retain the porous structure of DE, and GO nanosheets bind physically to the surface of DE. The adsorption experiments show that the kinetic data fit well with pseudo-second-order model. The adsorption isotherms follow the Freundlich isotherm model. The adsorption behavior of the GO-DE composites is an exothermic and spontaneous process. The GO-DE composite materials can be a promising candidate as an adsorbent for the removal of cationic dyes from wastewater. [ABSTRACT FROM AUTHOR] |
