MOF/MSN Composite as an Effective Adsorbent for Solid-Phase Microextraction Samplingof PAHs from Soil Samples

In this work, a new composite of MOFs (MIL-۸۸(Fe)) and MSNs (mesoporous silica materials) weresynthesized and characterized by FE-SEM, XRD, BET, TGA and FTIR techniques. The HS-SPME method is evaluatedfor sampling PAHs (Polycyclic aromatic hydrocarbons) compounds from polluted soil samples using theMOF/MSN fiber. Optimization of the extraction parameters including extraction temperature, extraction time,moisture content of the sample, desorption time and desorption temperature was carried out using a GC-FIDinstrument and a Box-Behnken design (BBD) method
