Application of magnetite–graphene oxide for wastewater treatment (original) (raw)

Graphene-Based Nanotechnologies for Energy and Environment, 2019

Abstract

Graphene oxide (GO) is a two-dimensional honeycomb lattice structure with numerous oxygen-containing functional groups on its surface. The theoretically predicted (2360 m2 g−1) and experimentally measured surface areas (∼700 m2 g−1) of GO make them attractive for environmental applications. In material science the research on graphene and their scaled-up reliable production have attracted a lot of interest. The possibility of conjugation of graphene and GO with inorganic nanomaterials to form composite has received particular attention for the advancement of wastewater treatment process. This chapter describes the preparation of magnetite GO and outlines the latest application in dispersive solid-phase extraction for environmental water remediation. It also highlights the challenges which limit their large-scale field applications and further challenges.
