Three dimensional phytic acid-induced graphene as a solid-phase microextraction fiber coating and its analytical applications for nerolidol in tea

Three dimensional phytic acid-induced graphene coating was prepared by hydrothermal synthesis and fabricated on a stainless-steel wire as a solid phase microextraction (SPME) coating. Compared with the commercial 100 μm PDMS and 85 μm CAR/PDMS fibers, the home-made SPME fiber exhibited excellent extraction efficiency for the analysis of nerolidol in tea samples.
