Recent advances of graphene-based sorptive materials in extraction: A review

In the past decade, graphene, as a two-dimensional adsorption material, had attracted much attention due to its large specific surface area, excellent thermal, chemical stability and high adsorption efficiency. It had great potential in extraction and was considered to be a revolutionary material in the future. In this review, the functionalization methods of graphene-based materials and their application and development in the field of sample pretreatment were reviewed. The characteristics and development prospects of various (micro) extraction technologies in recent years were introduced. Moreover, the applications of graphene and its derivatives as extraction materials in environmental pollution, food analysis and biomedicine were discussed. It provided a reference and guidance for the development of new graphene extraction materials. (c) 2021 Elsevier B.V. All rights reserved.
