摘要：
A novel solid-phase microextraction fiber was prepared using graphene oxide/β-cyclodextrin (GO/β-CD) composite as a coating material immobilized on a stainless steel wire using sol-gel technique. The coating has large surface area with uniform porous structure, stable performance at high temperature, and good coating preparation reproducibility. The prepared GO/β-CD sol-gel stainless steel fiber used as a headspace solid phase microextraction (HS-SPME) fiber was evaluated by the determination of organophosphate ester flame retardants (OPFRs) in water samples coupled to a gas chr...
