In situ hydrothermal growth of ytterbium-based metal-organic framework on stainless steel wire for solid-phase microextraction of polycyclic aromatic hydrocarbons from environmental samples.
In this paper, we report the use of a porous ytterbium-based metal-organic framework (Yb-MOF) coating material with good thermal stability for the headspace solid-phase microextraction (HS-SPME) of polycyclic aromatic hydrocarbons (PAHs) from environmental samples. The Yb-MOF thin films, grown in situ on stainless steel wire in solution, exhibited high selectivity and sensitivity toward PAHs. Under the optimal conditions, the novel fibers achieved large enrichment factors (130-2288), low limits of detection (0.07-1.67ngL(-1)), and wide range of linearity (10-1000ngL(-1)) for 16 PAHs in the tested samples. The novel fiber was successfully used in the analysis of PAHs in real environmental samples. These results demonstrated that Yb-MOF is a promising coating material for the SPME of PAHs at trace levels from environmental samples.
