Abstract

Abstract: Graphene with atomic layer of sp 2 -hybridized carbon atoms in a hexagonal structure has attracted multidisciplinary attention since its discovery. Due to the inherent advantages of large specific surface area and abundant functional groups, its derivative graphene oxide (GO) nanomaterials have achieved large-scale development in effective pollution treatment. In the past few years, novel GO-based nanomaterials through coupling with other nanomaterials have been synthesized with significant process and applied for efficient elimination of different kinds of pollutants. This paper aims to summarize recent research results on the excellent removal ability of GO-based nanomaterials for various heavy metal ions in aqueous solutions. The synthesis, adsorption process characteristics and interaction mechanism of the adsorbent are emphasized and discussed. The effects of various environmental conditions are outlined. At last, a brief summary, perspective and outlook are presented. This review is intended to provide some thrilling information for the design and manufacture of GO-based nanomaterials for the elimination of heavy metal ions from wastewater in environmental pollution management. Graphical abstract: Image 1086 Highlights: Synthesis and surface modification of GO-based composites are reviewed. Applications of different GO-based composites for metal ions elimination are reviewed. Interaction mechanism of metal ions with GO-based composites is discussed. Sorption capacities of metal ions on GO-based composites and other materials are compared. Perspective of GO-based composites in pollution management is summarized. Abstract : The synthesis of graphene oxide-based materials and their application in the efficient elimination of different metal ions are summarized and compared with other materials. The interaction mechanism is discussed in detail.
