Graphene-Based Nanomaterials: A Sustainable Material for Solid-Phase Microextraction (SPME) for Environmental Applications

Sample preparation is one of the essential step in analytical chemistry. Along with the advancement in sample preparation, analytical chemists pay more attention to the solid phase microextraction (SPME) due to its unique properties. SPME-based methods are economically beneficial and reproducible. The adsorbent plays an essential role in the extraction process. Graphene has received attention due to its unique physicochemical characteristics such as high surface-to-volume ratio, novel electrical and thermal stability, and highly porosity. Due to unique characteristics, graphene and graphene-based materials have been efficiently used as adsorbents in SPME. This review discusses graphene and graphene-based materials used in SPME.
