Cyclodextrin‐functionalized reduced graphene oxide as a fiber coating material for the solid‐phase microextraction of some volatile aromatic compounds

27.02.2015 | Shuaihua Zhang, Zhi Li, Chun Wang, Zhi Wang, Journal of Separation Science, 2015

A novel solid‐phase microextraction fiber was prepared for the first time by using a sol–gel technique with hydroxypropyl‐β‐cyclodextrin‐functionalized reduced graphene oxide as the fiber coating material. The results verified that the β‐cyclodextrin was successfully grafted onto the surface of ...
