Metal–organic frameworks (MOFs) have attracted recently considerable attention in analytical sample preparation, particularly when used as novel sorbent materials in solid-phase microextraction (SPME). MOFs are highly ordered porous crystalline structures, full of cavities. They are formed by inorganic centers (metal ion atoms or metal clusters) and organic linkers connected by covalent coordination bonds. Depending on the ratio of such precursors and the synthetic conditions, the characteristics of the resulting MOF vary significantly, thus drifting into a countless number of interesting materials with unique properties. Among astonishing features of MOFs, their high chemical and thermal stability, easy tuneability, simple synthesis, and impressive surface area (which is the highest known), are the most attractive characteristics that makes them outstanding materials in SPME. This review offers an overview on the current state of the use of MOFs in different SPME configurations, in all cases covering extraction devices coated with (or incorporating) MOFs, with particular emphases in their preparation.

Organic Framework

In this research, the metal–organic framework (MOF) as a solid phase was used for separation mercury [Hg (II)] inhuman serum sample by ultrasound assisted- Ionic Liquid-solid phase microextraction procedure (USA- IL-μ-SPE). Mercury extracted from serum sample by [Zn2(BDC)2(DABCO)]n as MOF at pH=7.8. Hydrophobic ionic liquid ([BMIM] [PF6]) was used as solvent trap for Hg-MOF-NC from the sample solution. The phase of Hg-MOF-NC was back extracted by 0.5 mL of HNO3 (0.2 mol L-1) and finally mercury concentration determined with cold vapor-atomic absorption spectrometry (CV-AAS) after dilution with 0.5 mL of DW. Under the optimal conditions, the linear range, limit of detection and preconcentration factor were obtained 0.02–5.5 µg L−1, 6.5 ng L−1 and 9.8 for serum samples, respectively (%RSD<5%). The validation of methodology was confirmed by standard reference materials (SRM).
