Analysis of trifluralin pesticide in food samples by MOF/COF hybrid solid-phasemicroextraction followed by ion mobility spectrometer

Metal-organic framework (MOF) based on manganese and melamine-rich covalent organic framework(COF) were combined, resulting in an effective nanocomposite sorbent of Mn-terephthalic acid (TA) /COF.Corona discharge ionization-ion mobility spectrometer (CD-IMS) was applied as a detection system fordetermination of trifluralin molecules. The limit of detection (LOD) ۰.۰۸ ng mL-۱ and linear dynamic range (LDR)۰.۲۵ - ۱۰.۰۰ ng mL-۱ were obtained
